Resumen
Une transition des sources d'énergie fossiles vers la production d'énergie renouvelable nécessite des systèmes de stockage qui compensent l'intermittence des sources d'énergie verte. La production d'hydrogène provenant de l'électrolyse de l'eau alimentée par l'électricité solaire ou éolienne est un vecteur d'énergie abondante, propre et renouvelable. De plus, l'énergie renouvelable en surplus peut être stockée dans des carburants ou des produits chimiques plus complexes. Liée à l'électrolyse, l'électro-réduction du CO2 (CO2R) produit des hydrocarbures à haute densité énergétique qui stockent é

Face au réchauffement climatique dû aux activités humaines et à l’utilisation de ressources fossiles, le besoin de trouver de nouvelles sources d’énergies décarbonées devient urgent.

One of the greatest challenges for the study of photocatalysts is to devise new catalysts that possess high activity under visible light illumination. This would allow the use of an abundant and green energy source, sunlight, to drive chemical reactions. Gold nanoparticles strongly absorb both visible light and UV light. It is therefore possible to drive chemical reactions utilising a significant fraction of full sunlight spectrum.

Resumen
Polymer electrolyte membrane fuel cells (PEMFC) are electrochemical devices which can directly convert the chemical energy of a fuel (such as hydrogen or a low-molecular weight alcohol) and an oxidant (i.e. oxygen) into electrical energy with high efficiency. Moreover, due their low operating temperature, they are suitable for automotive or portable applications. However, the slow kinetics of oxygen reduction reaction (ORR) requires the use of costly Pt-based catalysts at the cathode in order to obtain the desired power density values. Nevertheless, the cathode is still responsible for the mai

The presence of peripheral substituents on the macrocycle enhances the yield of the triplet state. Near infra-red absorptions of the solvents reveal that solvents which absorb around 1100 nm and around 1270 nm, quench the triplet state of the MPc derivative and singlet oxygen, respectively. Alth

Beginning with the discovery of graphene, two-dimensional materials have amassed a strong interest. Like graphene, transition metal dichalcogenides (TMDs) can be coaxed into atomically thin sheets which have some impressive properties.

Additionally, these materials lose their inversion symmetry as a monolayer. These unique properties make TMDs a strong candidate for being used in optoelect

The existence of complexes of that display non-innocence has been of interest in the field of coordination chemistry since the investigations of square-planar dithiolene complexes of the late transition metals in the 1960s. The ligands used in these systems are termed “non-innocent” when bound to a number of the late transition metals, because the orbital energy levels are similar to those of the central metal ion. This allows there to be significant electron delocalisation over the complex with the potential for the complexes to exist in a number of electronic states due to the combined elect

Resumen
Now, I will proceed with a very brief description of the two main parts that form this thesis work, which are inspired by some new possibilities that high pressure has opened for the synthesis of new phases and compounds. The relevance of these new materials from a practical point of view, lies in the possibility of having them recovered to ambient conditions and then used in a wide variety of technical applications. The two examples covered here, include a new class of transition-metal nitrides, and the synthesis of extended forms of CO2. In Chapter 3, it is shown that the new family

Resumen
Abstract The harmful emissions of chlorinated volatile organic compounds (CVOCs) originate only from man-made sources. CVOCs are used in a variety of applications from pharmaceuticals production to decaffeination of coffee. Currently, CVOC emissions are limited by strict legislation. For these reasons, efficient CVOC abatement technologies are required. Catalytic oxidation is very promising option for this purpose, since catalysts can be tailored to each case to maximize the efficiency and minimize the formation of unwanted products, such as dioxins or Cl2. The goal of this thesis was to study
