The electrocatalytic hydrogenation (ECH) of cyclohexanone into cyclohexanol has been studied in aqueous media with electrocatalysts on composites powders. These powders are formed of nanoaggregates of nickel obtained through a physical deposition under vacuum on particles of Al(OH)3, AlO(OH), and γ-Al2O3. The ECH reaction was done in a dynamic cell. Its yield is closely dependent on the nature of the non-metallic particles whose nature greatly influences the adsorption–desorption of the organic compounds involved in the reaction.Key words: electrocatalysis, aluminum oxide, aluminum hydroxide, hydrogenation, dynamic cell.[Traduit par la Rédaction]

Amorphous nickel hydroxides added anion (PO43-) has been prepared by chemical precipitation method combined with rapid quench technique. The morphology of the prepared samples were characterized by scanning electron microscope (SEM), and energy dispersive spectroscopy (EDS). The effect of anion on the electrochemical performance of the prepared nickel hydroxides were investigated by charge/discharge tests and cyclic voltammetry (CV). The results demonstrated that amorphous nickel hydroxide added PO43-has better electrochemical performance, such as higher discharge potential, better reaction reversibility, higher the charging efficiency, and better cyclic stability, than that of the pure amorphous nickel hydroxide.

In this work, we present a facile technique based on electrophoretic deposition (EPD) to produce transition metal hydroxide decorated carbon nanotubes (CNT) for electrochemical applications. We specifically explore the performance of nickel-cobalt hydroxides given their high activity, conductivity and stability as compared to the individual hydroxides. We exploit the high local pH at the negative electrodes during water-based EPD to form nanoparticles of nickel-cobalt hydroxides in situ on the CNT surface. We focus our work here on obtaining functional and conductive deposits on CNTs. The hydrophilic binderless deposits of Ni-Co double hydroxide decorated CNTs obtained here are used for non-enzymatic glucose detection. XPS data and electrochemical testing reveal difference in the deposited double hydroxide based on chronology of charging salt addition even at the same ratio. When cobalt and nickel salts are sequentially added at a ratio of 1:1, the deposited double hydroxides show excellent glucose sensitivity of ~3300μA/mM.cm2 at applied potential of 0.55V vs. Ag/AgCl reference electrode.

This review article summarizes the last few decades of research on nickel hydroxide, an important material in physics and chemistry, that has many applications in engineering including, significantly, batteries. First, the structures of the two known polymorphs, denoted as α -Ni(OH) 2 and β -Ni(OH) 2 , are described. The various types of disorder, which are frequently present in nickel hydroxide materials, are discussed including hydration, stacking fault disorder, mechanical stresses and the incorporation of ionic impurities. Several related materials are discussed, including intercalated α -derivatives and basic nickel salts. Next, a number of methods to prepare, or synthesize, nickel hydroxides are summarized, including chemical precipitation, electrochemical precipitation, sol–gel synthesis, chemical ageing, hydrothermal and solvothermal synthesis, electrochemical oxidation, microwave-assisted synthesis, and sonochemical methods. Finally, the known physical properties of the nickel hydroxides are reviewed, including their magnetic, vibrational, optical, electrical and mechanical properties. The last section in this paper is intended to serve as a summary of both the potentially useful properties of these materials and the methods for the identification and characterization of ‘unknown’ nickel hydroxide-based samples.

In this study, the mechanism of nickel nanoparticle formation from its hydroxide was analyzed. Metallic nickel nanoparticles were obtained through the hydroxide’s reduction under hydrogen. Nickel hydroxides were produced from nickel (II) nitrate hexahydrate and NaOH by deposition under various initial conditions. The influence of washing treatment on the dispersion of obtained nickel powders was studied. The washing procedure of precipitates was carried out by centrifugation, ultrasonic treatment, and decantation. X-ray diffractometry, transmission electron microscopy, low-temperature nitrogen adsorption, infrared spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy methods were used for nanoparticle characterization. Based on the resulting data, a model of the Ni(OH)2 aggregate structure after deposition was proposed. The number of nickel hydroxide particles required to form one nickel nanoparticle was estimated, and a model of its formation was proposed.

Mg-substituted α- and β-phase nickel hydroxides with high specific capacitance and good stability have been synthesized via sacrificial metal-based replacement reaction. 2D α- and β-phase nickel-magnesium hydroxide (NiMg-OH) have been synthesized by sacrificing magnesium (Mg) powder with nickel salt aqueous solutions. Interestingly, the phase of the obtained NiMg-OH can be controlled by adjusting the nickel precursor. As well, the Mg powder is used not only as Mg source but also alkali source to form NiMg-OH. The α-phase nickel-magnesium hydroxide sample (α-NiMg-OH) exhibits lager surface area of 290.88 m2 g–1. The electrochemical performances show that the α-NiMg-OH presented a superior specific capacitance of 2602 F g–1 (1 A g–1) and β-phase nickel-magnesium hydroxide sample (β-NiMg-OH) exhibits better stability with 87% retention after 1000 cycles at 10 A g–1. The hybrid supercapacitor composed of α-NiMg-OH and activated carbon (AC) display high storage performance and cycle stability, it presents 89.7 F g–1 (1 A g–1) and of 0–1.6 V potential window and it maintains capacitance retention of 84.6% subsequent to 4000 cycles.

Nickel hydroxide samples obtained by strong alkali precipitation are replete with stacking faults. The local structures of the stacking faults resemble the stacking patterns of different polytypic modifications that are theoretically possible among the layered hydroxides. This resemblance becomes a basis for the classification of stacking faults into different types. Each type of stacking fault produces a characteristic non-uniform broadening of peaks in the X-ray powder diffraction pattern of nickel hydroxide. DIFFaX simulations aid the classification and quantification of stacking faults. Hydrothermal treatment of a poorly ordered nickel hydroxide slurry at different temperatures (338–473 K) and different durations (5–48 h) shows that the stacking faults are removed in a stepwise manner. The as-precipitated sample has 17–20% stacking faults of the 3R 2 variety, which evolve into the 2H 2 type at 413 K. The 2H 2 stacking faults persist up to 443 K. The stacking faults are completely removed only at 473 K. At this temperature an ordered β-Ni(OH)2 phase is observed.

β-phases of nickel hydroxide and cobalt hydroxide samples crystallize in cadmium iodide type structure. β-cobalt hydroxide on oxidation generates β-CoOOH which crystallized in 3R1 polytype while the structure of β-phase of NiOOH polytype is less well understood. β- and βbc-phases of nickel hydroxide samples were prepared by using ammonium hydroxide and sodium hydroxide as precipitating agents. Powder X-ray diffraction data shows that β-phase of nickel hydroxide is perfectly crystalline in nature while βbc-phase of nickel hydroxide is poorly ordered. β- and βbc-phases of nickel hydroxide samples were subjected to chemical oxidation using sodium hypochlorite. The oxidized phases of β- and βbc-phases of nickel oxyhydroxide are highly disordered and the broadening of reflections in the powder X-ray diffraction patterns is due to the presence of structural disorder, variations in the crystallite size, and strain. On reduction of β- and βbc-phases of nickel oxyhydroxide, the powder X-ray diffraction patterns visually match the powder X-ray diffraction data of the pristine phases of β- and βbc-phases of nickel hydroxide indicating that the β-phase of nickel hydroxide does not transform to βbc-phase of nickel hydroxide, but the particle sizes are significantly affected.

In spite of structural similarities exhibited by nickel hydroxide and cobalt hydroxide samples, former is a good electrode material and exchanges 1e-/Ni while latter does not show any reversibility. Presence of small amount of other metal ions such as nickel or zinc in the lattice of cobalt hydroxide or as a biphasic mixture of cobalt hydroxide-nickel hydroxide/cobalt hydroxide- zinc oxide, exchange up to 0.2 to 0.24e- exchange compared to pure cobalt hydroxide which shows 0.1 e- exchange.

Amorphous nickel hydroxide powders doped with rare earth La3+ and Al3+ were synthesized by the combined chemical precipitation and rapid freezing method. The microstructure of the samples was characterized by XRD and Raman spectra. The electrochemical performance of the prepared samples was analyzed by electrochemical impedance spectroscopy and charge-discharge tests. The results showed that this amorphous nickel hydroxide codoped with La3+ and Al3+ had more structural defects than those of the undoped amorphous nickel hydroxide and La3+ singly doped amorphous nickel hydroxide. These abundant structural defects with La3+ and Al3+ codoped amorphous nickel hydroxide decreased the electrochemical impedance spectroscopy and improved the electrochemical reversibility of the amorphous nickel hydroxide electrode.

Ce travail est peut être séparé en deux parties. Dans la première, nous rapportons l'étude menée sur un composé modèle d'hydroxyde de Nickel. La caractérisation de ce composé par diffraction X montre qu'il possède une cristallinité supérieure aux hydroxydes de nickel habituellement utilisés. L'observation au microscope électronique à balayage révèle que la poudre est constituée de grains hexagonaux, de dimension supérieure au micromètre, formés de monocristaux, eux aussi hexagonaux, empilés de façon très ordonnée. Les mesures électrochimiques montrent quant à elles que les composés modèles présentent des propriétés redox intéressantes. La morphologie très particulière de ce composé confère à cet hydroxyde de nickel un comportement de type monocristal en spectroscopie Raman. Des mesures in-situ, couplant voltamétrie cyclique et spectroscopie Raman, réalisées sur ce composé modèle, ont donc été mises en place. Les premiers résultats montrent que ces expériences pourraient nous aider à améliorer notre compréhension des mécanismes redox fondamentaux mis en jeu.Dans la deuxième partie, nous étudions le comportement électrochimique d'une électrode de nickel lorsque l'électrolyte (i.e. KOH 7N) est saturé en zinc. Des électrodes de type industriel ont été préparées à partir d'un hydroxyde de Nickel standard et non dopé, puis cyclées en condition galvanostatique. Les échantillons ainsi obtenus ont ensuite été caractérisés par MEB, DRX, IR et EXAFS. Cette dernière technique qui s'est avérée être la plus appropriée pour l'analyse de ces matériaux d'électrodes très hétérogènes nous a ainsi permis d'apporter des réponses pertinentes sur l'insertion du zinc dans la structure cristalline de Ni(OH)2
This work may be separated in two parts. First, we report the study of a model compound of nickel hydroxide. X-ray diffraction shows that this compound has a better crystallinity than the standard nickel hydroxides used in commercial battery. Scanning Electron Microscopy revealed that the powder of this model hydroxide is composed of hexagonal grains whose dimension is larger than micrometer and who are formed of single-crystals, also hexagonal, stacked in a well ordered way. The electrochemical measurements show that this nickel hydroxide exhibit interesting redox properties. The particular morphology of the compound gives single-crystal type behavior in Raman spectroscopy. Therefore, in-situ measurements combining electrochemical measurements and Raman spectroscopy, performed on a single microscopic hexagonal plate, are proposed. Preliminary results emphasize that this experiment may help us to improve our understanding of the fundamental redox mechanism taking place in nickel hydroxide.Secondly, we study the electrochemical behavior of a nickel electrode in the presence of Zinc in the electrolyte. Industrial-type electrodes were prepared from a standard undoped nickel hydroxide. Then, samples obtained after electrochemical test were characterized by SEM, XRD, IR and EXAFS. The later which turned out to be the most appropriate for the analysis of our electrode materials, allowed us to get deeper insights in the insertion of zinc in the structure of Ni(OH)2

Les accumulateurs alcalins sont connus pour leur fiabilite. La constance de leur tension de decharge, avantageuse en soi, se revele etre un handicap pour la determination de l'etat de charge. Nous avons etudie par spectroscopie d'impedance l'electrode a hydroxyde de nickel (e. H. N. ) de ces accumulateurs et en proposons une modelisation susceptible d'aider a la determination dudit etat de charge. La reaction de charge/decharge de l'e. H. N. Peut etre consideree comme une deinsertion/insertion du proton dans la matrice lamellaire de l'hydroxyde. L'e. H. N. Possede de fait une conduction mixte electronique et protonique associee a un comportement bloquant a basse frequence. Nous proposons ainsi une modelisation de type ligne de transmission incluant les quatre resistivites electroniques et protoniques de la matiere active dans les etats charge et decharge ainsi qu'une capacite interne provenant des interactions electrons-protons. Cette derniere depend peu du taux de charge et de la texture de l'electrode mais est proportionnelle a la masse de matiere active (environ 1000 farads par gramme). Les spectres d'impedance electrochimique ne permettent cependant pas de determiner commodement l'etat de charge car ils varient peu en cours de cyclage. Aussi une methode derivee, l'impedance transverse, a ete mise au point: l'impedance est mesuree entre deux contacts diametralement opposes de l'electrode. Il s'ensuit une modification plus nette des diagrammes avec le taux de charge. Cette methode suppose toutefois la mise place de connexions fiables a l'interieur de l'accumulateur. Une troisieme technique, sans contact cette fois, fondee sur les courants de foucault, a donc ete developpee. Dans des conditions adequates, l'impedance de la bobine excitatrice externe est sensiblement proportionnelle au taux de charge

Les supercondensateurs, en tant que dispositifs de stockage d'énergie, ont attiré une grande attention dans notre vie quotidienne pour combler l'écart entre les batteries et les condensateurs. Par conséquent, la préparation d'électrodes en matériaux composites à hautes performances pour les supercondensateurs joue un rôle vital dans leurs futurs développements technologiques. Dans ce contexte, les hydroxydes doubles lamellaires (HDL) et Ni(OH)2 ont été reconnus comme des électrodes prometteuses pour les supercondensateurs en raison de leurs réactions redox rapides et de leur comportement de type batterie.Le chapitre 1 donne un bref aperçu historique ainsi que les principes et le mécanisme de stockage d'énergie, les matériaux d'électrode des supercondensateurs, et les méthodes de caractérisation correspondantes.Le chapitre 2, après un bref rappel sur la synthèse et l’utilisation de matériaux à base d’HDL comme électrodes de supercondensateurs, on décrit la préparation d’HDL à base de Ni comme électrodes pour les supercondensateurs. Premièrement, des HDLs à base de NiFe sur mousse de Ni (NF) recouverte d'oxyde de graphène réduit (LDF NiFe/rGO/NF) ont été préparées par une méthode de dépôt électrochimique. L’électrode NiFe HDL/rGO/NF présente une capacité spécifique de 585 C g-1 à une densité de courant de 5 A g-1. Dans la deuxième partie de ce chapitre, nous décrivons la synthèse hydrothermale d’HDLs à base de NiAl enrobées sur des sphères de carbone (CS) supportées par des électrodes en mousse de Ni (NiAl DHL@CS/NF). La performance des matériaux préparés en tant qu'électrodes sans liant dans des supercondensateurs a été évaluée. Le matériau d'électrode NiAl DHL@CS/NF présente une capacité surfacique de 1042 mC cm-2 à 1 mA cm-2, beaucoup plus élevée comparée aux valeurs de capacités surfaciques de NiFe HDL@CS/NF (705.8 mC cm-2) et de NiCr LDHs@CS/NF (814.9 mC cm-2) à 1 mA cm-2. Enfin, un matériau composite à base de NiMnCr sur un substrat de mousse de nickel recouvert de sphères de carbone (NiMnCr HDL@CS/NF) a été préparée en utilisant un processus hydrothermal en deux étapes. Le nanocomposite ainsi obtenu a été investigué comme électrode dans un supercondensateur et présente une capacité spécifique de 569 C g-1 à 3 A g-1 avec une bonne stabilité. De plus, un supercondensateur hybride a été fabriqué en utilisant NiMnCr HDL@CS/NF comme électrode positive et FeOOH déposé sur NF (FeOOH/NF) comme électrode négative. Le dispositif présente une densité d'énergie de 48 Wh kg-1 à une densité de puissance de 402.7 W kg-1. Dans le chapitre 3, des électrodes sans liant Ni(OH)2@CuO sur une mousse de cuivre ont été synthétisées par un processus en deux étapes à température ambiante. Nous avons étudié l’effet du temps de dépôt (30, 50, 90, 150 et 200 s) sur le comportement électrochimique des électrodes obtenues. Parmi tous les échantillons, Ni(OH)2@CuO@Cu-150 présente la plus grande capacité surfacique de 7063 mC cm-2 à 20 mA cm-2, et a donc été choisi comme électrode positive dans un supercondensateur hybride. En utilisant de l'oxyde de graphène réduit dopé à l’azote sur de la mousse de nickel (N-rGO/NF) comme électrode négative, un supercondensateur hybride a été assemblé. Il présente une bonne flexibilité, une stabilité cyclique et une densité d'énergie surfacique élevée de 130.4 μWh cm-2 à une densité de puissance de 1.6 mW cm-2.Une conclusion générale rappelle les principaux résultats obtenus dans ce travail de thèse sur l'application de composites d'hydroxydes doubles lamellaires à base de Ni en tant qu’électrodes dans des dispositifs de stockage d'énergie, et présente quelques perspectives envisageables à la lumière de ces travaux (chapitre 4)
Supercapacitors, as energy storage devices, have drawn great attention in our daily life to bridge the gap between batteries and capacitors. Therefore, the preparation of high-performance material electrodes for supercapacitors plays a vital role in the future technological developments. In this context, layered double hydroxides (LDHs) and Ni(OH)2 have been recognized as promising electrodes for supercapacitors, owing to their fast redox reaction and battery-type behavior.The Chapter 1 of my PhD work gives a brief historic overview, principles and mechanism of energy storage, electrode materials of supercapacitors and the corresponding characterization methods. In Chapter 2, after a brief introduction on LDHs and their investigation as electrode materials in supercapacitors, we summarize our results obtained on Ni-based LDHs as electrodes for supercapacitors. Firstly, NiFe LDHs on Ni foam (NF) coated with reduced graphene oxide (NiFe LDHs/rGO/NF) was prepared by electrochemical deposition method. NiFe LDHs/rGO/NF achieved enhanced specific capacity (585 C g-1 at a current density of 5 A g-1). Additionally, a flexible asymmetric supercapacitor was assembled using NiFe LDHs/rGO/NF as the cathode and mesoporous carbon (MC) coated on NF as the anode. The supercapacitor exhibited an energy density of 17.71 Wh kg-1 at a power density of 348.49 W kg-1. Secondly, NiAl LDHs coated on carbon spheres (CS) supported by Ni foam (NiAl LDHs@CS/NF) electrodes were synthesized by a facile hydrothermal method. The performance of the prepared materials as binder-free electrodes in supercapacitors was assessed. The NiAl LDHs@CS/NF electrode achieved the largest areal capacity (1042 mC cm-2), as compared to the areal capacity values attained by NiFe LDHs@CS/NF (705.8 mC cm-2) and NiCr LDHs@CS/NF (814.9 mC cm-2) at 1 mA cm-2. Therefore, a hybrid supercapacitor device comprising NiAl LDHs@CS/NF as the positive electrode and N-doped reduced graphene/NF as the negative electrode was assembled, which attained an energy density of 43 μWh cm−2 at a power density of 0.805 mW cm−2. The hybrid supercapacitor was successfully applied to operate a windmill device continuously for 32 s. Finally, NiMnCr LDHs-carbon spheres modified Ni foam (NiMnCr LDHs@CS/NF) nanocomposite was prepared using a two-step hydrothermal process and exhibited a high specific capacity of 569 C g-1 at 3 A g-1 with good reversibility and stability. Furthermore, a hybrid supercapacitor was fabricated using NiMnCr LDHs@CS/NF as the positive electrode and FeOOH coated on NF (FeOOH/NF) as the negative electrode. The energy storage device reached an energy density of 48 Wh kg-1 at a power density of 402.7 W kg-1. In Chapter 3, Ni(OH)2@CuO@Cu foam binder-free electrodes were fabricated by a two-step process at room temperature with various deposition times (30, 50, 90, 150 and 200s). Among all the samples, Ni(OH)2@CuO@Cu-150 exhibited the largest areal capacity of 7063 mC cm-2 at 20 mA cm-2, and was therefore chosen as the positive electrode in a hybrid supercapacitor. Using N-doped reduced graphene oxide on nickel foam (N-rGO/NF) as the negative electrode, a hybrid supercapacitor was assembled. It displayed good flexibility, cycling stability and high areal energy density of 130.4 μWh cm−2 at a power density of 1.6 mW cm−2.In conclusion, all the results obtained in this thesis imply the promising potential application of Ni-based hydroxide composites as energy storage devices and provide valuable highlights to the exploration of new composite materials for supercapacitor electrodes in future works (Chapter 4)

Les composés électrochomes changent de couleur en fonction d'une tension qui leur est appliquée. La tenue en cyclage de couches minces à base de NiO, électrochrome cathodique, dépend fortement de la température et de la pression de dépôt. D'autre part la proportion de phase électrochimiquement active dépend fortement de l'épaisseur des couches. Selon le modèle proposé NiO en milieu KOH se transforme en hydroxyde de nickel Ni(OH)2 puis dans la phase de coloration en oxyhydroxyde NiOOH avant de revenir à sa forme réduite durant la phase décoloration. À la fin de ce cycle, des traces de phase colorée persistent. Nous avons développé des nouvelles méthodes numériques d'analyse des spectres d'absorption de rayons X, caractérisant la structure locale autour du nickel dans ces phases non cristallisées, afin de déterminer les concentrations des diverses espèces au cours du cycle. Aucune des méthodes habituellement pratiquées, comme la combinaison linéaire d'espèces modèles par la méthode des moindres carrés linéaire, et la méthode d'Analyse en Composantes Principales, ne sont adaptées aux cas de spectres fortement corrélés comme les oxydes-hydroxydes de nickel. Nous montrons qu'il est possible d'améliorer la méthode des moindres carrés en utilisant un algorithme original : " la méthode des Moindres Carrés Linéaire Progressive ". La base de cette méthode est fondée sur l'étude statistique des erreurs et corrélations. Ce travail a permis de valider le modèle électrochimique et d'évaluer pour la première fois la concentration en NiOOH dans la phase réduite, signature de l'irréversibilité. Seule, la présence avant cyclage de Ni(OH)2 dans les films de NiO n'a pu être expliquée

Actuellement, les supercondensateurs sont au centre de beaucoup de recherches. Ils offrent une solution potentielle pour le stockage réversible de l´énergie que ce soit pour le domaine spatial, aéronautique ou encore le transport (véhicules hybrides). Un axe de recherche important, visant à augmenter les densités d'énergie et de puissance, est consacré aux systèmes oxydes de métaux de transition /charbon actif (C) asymétriques. Les systèmes à base de RuO2 présentent les capacités les plus élevées, supérieures à 700 F/g, mais leur coût et leur toxicité limitent leur application aux petits appareils électroniques. Des oxydes moins coûteux tels que les oxydes de cobalt (notamment Co3O4), MnO2, V2O5, Fe3O4, NiO, Ni(OH)2, ainsi que des polymères conducteurs électroniques, ont été étudiés de manière approfondie au cours des dernières décennies jusqu’à être utilisés, pour certains, dans des dispositifs commerciaux. Mais aucun système n’a été aussi étudié que le C / MnO2. En effet, il a été démontré que ce dernier est particulièrement intéressant car il peut fonctionner dans des milieux aqueux à des tensions pouvant aller jusqu’à 2V tout en gardant une bonne stabilité électrochimique durant le vieillissement. Néanmoins, les performances du système, en particulier en termes de densité de puissance, sont limitées à cause de la mauvaise conductivité électronique du MnO2. Il est possible de surmonter ce problème en ajoutant à l’oxyde de manganèse, des matériaux conducteurs à base de carbone (noir de carbone, nanotubes de carbone…) ou encore, en développant des stratégies de greffage ou de décoration plus élaborées. La combinaison d’oxydes avec des espèces carbonées est très largement rapportée dans la littérature alors que le mélange d’oxydes de différente nature l’est beaucoup moins. Nous proposons dans ce projet de synthétiser et de développer des matériaux originaux améliorant, par un effet synergique, les propriétés intéressantes du manganèse, du cobalt et de l'oxyde / hydroxyde de nickel. Les inconvénients de chaque composant étant compensés par les bonnes propriétés complémentaires des autres. Nous cherchons à réunir en un seul matériau (ou composite), le bon comportement pseudocapacitif du manganèse, la bonne conductivité électronique associée aux oxydes de cobalt, la grande capacité de l'hydroxyde de nickel ainsi que les propriétés de conduction du carbone. Ce projet de doctorat vise à concevoir et à fabriquer de nouvelles classes d'électrodes composites hybrides basées sur des assemblages de graphène (pour la capacitance renforcée à double couche) et d'oxydes poreux de métaux de transition (pour une capacité faradique supplémentaire due à de multiples processus rédox réversibles). Les avantages combinés du graphène et des oxydes de métaux de transition permettront aux supercondensateurs à haute densité d'énergie de travailler dans des électrolytes aqueux respectueux de l'environnement ce qui est, aujourd’hui, un besoin reconnu
Supercapacitors are the focus of much research at the present time. They offer a potential solution for reversible energy storage in the fields of space, aircrafts or transportation (hybrid vehicles). An important research line, aiming at increasing both energy and power densities, is devoted to asymmetric transition metal oxides / activated carbon (C) systems. RuO2-based devices exhibit the highest capacitance, more than 700 F/g, but their cost limits the applications to small electronic devices. Less expensive oxides such as cobalt oxides (especially Co3O4), MnO2, V2O5, Fe3O4, NiO, Ni(OH)2, as well as electrically conducting polymers, have been extensively studied in the past decades, or used in commercial devices; they EACH exhibit each drawbacks and advantages with regard to applications. But no system has been investigated as much as the C/MnO2 one, which is particularly interesting because it can work in aqueous media at tensions up to 2 V, and high stability in ageing has been demonstrated. Nevertheless, the performances of the system, especially in terms of power density, are limited by the poor electronic conductivity of MnO2. This problem is usually solved by simply mixing conductive carbon materials (carbon black, CNTs…) with MnO2 or by developing more elaborated grafting or decoration strategies. The combination of oxide and carbonaceous species is widely reported in the literature, whereas combining oxides with different natures is less frequently encountered. We propose in this project to synthesize and develop original materials enhancing, through a synergistic effect, the interesting properties of manganese, cobalt and nickel oxide/hydroxide, the drawbacks of each component being overbalanced by the good complementary properties of the other components. We aim at gathering in one single material (or composite), the good pseudocapacitive behavior of manganese, the good electronic conductivity associated to cobalt oxides, the high capacity of nickel hydroxide, as well as the enhanced conduction properties of carbon. The present PhD project aims at designing and manufacturing new classes of hybrid composite electrodes based on assemblies of graphene (for enhanced double layer capacitance) and porous transition metals oxides (for additional faradaic capacitance due to multiple reversible redox processes) directly applied on metallic current collectors. The combined advantages of graphene with those of transition metals oxides will enable supercapacitors with high energy density, working in environmentally friendly aqueous electrolytes, which are an acknowledged need
A procura crescente de energia em setores distintos, como residencial, transporte e industrial, bem como a proliferação de fontes renováveis de produção de energia, exigem novos e mais eficientes dispositivos de armazenamento de energia. Consequentemente, tem-se observado um interesse crescente na produção e engenharia de materiais para armazenamento de energia. Muito dos esforços de R&D estão centrados no desenvolvimento de materiais nanoestruturados que possam responder aos requisitos da aplicação, tais como densidade de energia, densidade de potência e estabilidade face à ciclagem do dispositivo. Presentemente são muitos os materiais investigados como potenciais candidatos para elétrodos para dispositivos de armazenamento de energia por via eletroquímia, nomeadamente baterias, condensadores, pseudocondensadores ou supercondensadores. O objetivo do presente trabalho é produzir e estudar novos materiais com uma resposta eletroquímica intermédia entre um elétrodo típico de supercondensador e um elétrodo típico de bateria, também conhecidos como elétrodos híbridos. Por essa razão, selecionaram-se hidróxidos e óxidos de níquel e cobalto devido à sua elevada atividade eletroquímica e baixo custo. Estes materiais foram combinados com derivados de grafeno, que exibem alta condutividade e elevada área superficial ativa. Portanto, este trabalho foca a síntese e caracterização fisico química e eletroquímica de hidróxidos e óxidos de níquel-cobalto nanoestruturados e sua combinação com óxido de grafeno reduzido para aplicações de armazenamento de energia. A síntese foi efectuada por duas vias distintas: eletrodeposição e exfoliação. A eletrodeposição é usada para obter hidróxidos e óxidos de níquel-cobalto em combinação com óxido de grafeno reduzido. Os resultados evidenciam um efeito sinérgico quando o óxido de grafeno reduzido é combinado com o (hidr)óxido de níquel- cobalto, isto é, um aumento na capacidade, condutividade e estabilidade do compósito quando comparado com o (hidr)óxido de níquel-cobalto. Neste trabalho é dada especial atenção à espectroscopia de impedância eletroquímica que foi utilizada para avaliar os fenômenos que ocorrem durante a carga e descarga contínua e compreender os processos que ocorrem no material ativo e que resultam na sua degradação. O hidróxido de níquel-cobalto é também preparado por exfoliação, em meio aquoso, por meio da intercalação de lactato, enquanto o tetra-butilamónio é utilizado na exfoliação do óxido de níquel-cobalto. A resposta eletroquímica é avaliada em diferentes eletrólitos após reconstrução. Os resultados revelam a influência das espécies intercaladas durante o processo de exfoliação: quando a exfoliação é realizada para fins de armazenamento de energia, as espécies intercaladas e a força da interação com o material ativo devem ser consideradas de antemão para evitar o bloqueio superficial ou inibição da interação elétrodo-eletrólito. Os resultados mostraram que a exfoliação é uma rota promissora para aumentar a área de superfície ativa dos materiais, um parâmetro crítico no desempenho eletroquímico dos materiais dos eletrodos. Nesta dissertação é também estudado o mecanismo de carga-descarga do hidróxido de níquel-cobalto, que ainda não está completamente entendido. Assim, compreender esse mecanismo é um passo crítico para otimizar a morfologia e o desempenho do material e para projetar futuros dispositivos de armazenamento de energia. Para esclarecer os processos que ocorrem durante a carga, aplica-se o modelo de Mott-Schottky foi aplicado parade modo a avaliar a variação da conductividade do material e da sua capacidade na interface elétrodo-eletrólito.

Resumo:
Ce travail est consacre à la synthèse et à la caractérisation de nouveaux hydroxydes de nickel substitues au cobalt et à l'aluminium. La présence de 25% d'ions trivalents permet d'assurer la cohésion de la structure de type alpha, ainsi que la stabilité chimique de ces matériaux en milieu alcalin concentre. L'étude électrochimique montre que le couple alpha/gamma est parfaitement stabilise lorsque le taux d'aluminium est supérieur a 15%. En revanche, pour des taux inférieurs, il se produit une évolution progressive du couple alpha/gamma vers le couple bêta (II)/bêta (III), accompagnée d'une baisse de la capacité. Ce phénomène est du à une ségrégation des ions cobalt qui mené a une démixtion de la phase alpha initiale en un mélange d'hydroxyde de nickel et d'oxymydroxyde de cobalt de type bêta. Le système des oxyhydroxydes de cobalt a été étudié. Deux phases notées bêta (III) et gamma ont été préparées par chimie douce. Leurs structures ainsi que leurs propriétés électriques ont été clairement mises en évidence. Enfin, leur utilisation comme conducteur électronique post-rapporte a l'hydroxyde de nickel a conduit a des performances électrochimiques prometteuses sur le plan applique.

Ce travail concerne la preparation de poudres de nickel par le procede polyol. Dans ce procede un precurseur est mis en suspension dans un polyol qui joue le role de solvant et de reducteur ; le metal precipite alors par nucleation homogene et croissance a partir de la solution. L'objectif etait de preparer des poudres de nickel monodisperses de taille et de forme controlees a partir de precurseurs hydroxydes et hydroxy-carbonates de nickel. Ces precurseurs ont ete caracterises par diffraction x, microscopie electronique, ir, dsc, tg, mesure de surfaces specifiques et analyses chimiques et le procede polyol a ete optimise pour l'utilisation de ces precurseurs. Des poudres avec des particules spheriques et des diametres variant dans le domaine micronique et submicronique ont ete obtenues soit en jouant sur la temperature de reaction (nucleation homogene) soit en controlant le nombre de germes formes (nucleation heterogene). L'application d'un champ magnetique durant la reaction avec l'acetate de nickel a permis de modifier la morphologie des particules et a abouti a la formation de filaments de nickel de 15 m de long et de 1 m de diametre
