Étude des effets morphologiques sur la dynamique des porteurs de charge et les sites actifs de surface dans les films minces de ferrite à l’aide de la spectroscopie de photoluminescence résolue en temps et des techniques de titrage de surface
This proposal seeks to explore the synthesis and characterization of thin film titania/ferrite Z-scheme materials, with an emphasis on elucidating the impact of morphology on charge carrier dynamics and surface active sites, thereby unraveling its influence on CO2 reduction performance in a photoelectrochemical (PEC) cell. The kinetics of electron and hole pairs in ferrite films will be investigated through time-resolved photoluminescence (TRPL) and electron paramagnetic resonance (EPR) techniques, providing insights into how morphological variations affect charge carrier behavior. Surface titration methods will be employed to identify active redox sites in the Z-scheme photo(electro)catalysts. The films will be synthesized using dip coating, spray coating, and spin coating techniques, and the relationship between fabrication methods and surface electronic properties will be established. Additionally, the correlation between PEC performance, charge carrier dynamics, and surface active sites of ferrite films will be thoroughly examined. This project seeks to enhance the efficiency of CO2 photo(electro)conversion technologies by bridging critical knowledge gaps in the real-time dynamics and surface activity of Z-scheme catalytic powders and films, with a focus on their synthesis and performance. Successful outcomes could pave the way for significant advances in the renewable energy-driven production of sustainable chemicals, making a meaningful contribution to climate change mitigation efforts.
