Nguyen, Thi Quyen. « Développement de photoélectrodes hybrides via l'assemblage d'un photosensibilisateur à base de ruthénium et d'un nanocatalyseur métal-oxyde métallique pour la génération d'O2 solaire ». Thesis, Toulouse 3, 2021. http://www.theses.fr/2021TOU30046.
In this work, different nanostructured catalytic systems have been synthesized by an organometallic approach to produce nanoparticles (NPs) of small size and narrow size distribution, and their catalytic activity in the water oxidation reaction has been evaluated. First Fe NPs stabilized by oleic acid were synthesized that displayed an average size of ca. 10 nm ± 1.1 nm. A gamma-Fe_2O_3 oxide layer ca. 2.6 nm thick has been formed at their surface to obtain Fe@FeOx core-shell structure of ca. 11.5 ± 2.3 nm in diameter. Despite their hydrophobicity, these nanoparticles showed good electrocatalytic activity in alkaline conditions. As the gamma-Fe_2O_3 oxide shell is well adapted to the grafting of phosphonic groups, these Fe@FeOx NPs were grafted with different aminophosphonic acids in order to transfer them into water. Preliminary assessment of their catalytic activity showed improved activity for the NPs functionalized by 3-aminopropylphosphonic acid which opens promising prospects. Subsequently, a Ru-phenanthroline light-harvester with a pendant phosphonate group was synthesized and grafted onto the Fe@FeOx core/shell NPs to afford a novel hybrid photoanode for solar-driven water splitting. Mono- and biphasic processes were investigated to graft the Ru-complex at the surface of the NPs. The monophasic process was found to be more efficient as it provided a higher grafting density at the surface of the NPs (respectively 56 and 9 Ru per nanoparticles for the mono and biphasic processes). Photoelectrochemical measurements showed that the hybrid nanocatalyst comprising the highest Ru content was ca. 9-fold more catalytically active than a simple mixture between a ruthenium polypyridyl photosensitizer bearing no grafting group and the Fe@FeOx nanoparticles, and 40-fold more active than the pristine Fe@FeOx NPs. The performance enhancement could be attributed to a more efficient electron transfer between the ruthenium polypyridyl photosensitizer and the Fe@FeOx water oxidation catalyst thanks to the covalent bonding between these two components. The covalent grafting was found to improve not only the photocatalytic activity but also the stability of the system. Finally, amorphous NiFe NPs (diameter ca. 4 nm) with two different ratios between Ni and Fe (Ni_0.5Fe_0.5 NPs and Ni_0.68Fe_0.32 NPs) were synthesized, oxidized in air and grafted with 3-aminopropylphosphonic acid in order to obtain hydrophilic systems. The electrocatalytic activity of these water-soluble NPs was studied in alkaline solution, in comparison with that of crude NiOx NPs, FeOx NPs, and Ni_0.1Fe_0.9Ox NPs. The water soluble NPs containing 32 % of Fe (Ni_0.68Fe_0.32Ox) showed the highest activity and a good durability in alkaline solution. These characteristics make these amorphous NPs potentially applicable in photoelectrochemical cells for water splitting

La contaminación ambiental mediante compuestos policlorados aromáticos y alifáticos es de gran preocupación. La reacción de hidrodecloración catalítica selectiva (HDC) se presenta como una nueva tecnología eficaz para una eliminación segura de estos tipos de compuestos orgánicos clorados. Es por ello, que este trabajo de investigación se ha enfocado en el estudio de nuevos catalizadores activos, selectivos y estables en diferentes reacciones de hidrodecloración de dos familias de compuestos orgánicos clorados: 1,2,4-triclorobenceno (1,2,4-TCB-compuestos aromáticos clorados) y el tricloroetileno (representativo de un compuesto clorado alifático). La primera parte de la tesis relacionadas con el HDC de 1,2,4-TCB, tiene como objetivo la obtención de catalizadores activos y estables para la hidrogenación del enlace C-Cl en compuestos aromáticos y la obtención final del compuesto aromático orgánico declorado. Mientras que la segunda parte tiene por objeto la obtención de catalizadores que permitan una gran selectividad a etileno y no hacia etano (hidrogenación profunda del tricloroetileno) durante la HDC de tricloroetileno. Por otra parte se ha realizado un estudio profundo en la síntesis de estos nuevos catalizadores, así como en la caracterización de los centros activos de dichos catalizadores, para su correlación con la actividad, selectividad y estabilidad de dichos catalizadores. Presenta ideas originales, lo que podría encontrar una aplicación práctica, para el tratamiento de compuestos órgano-halogenados contaminantes.
