Summary
Following "Photochemistry I", this course introduces the current theoretical models regarding the dynamics of electron transfer. It focuses then on photoredox processes at the surface of solids. Current technological applications, as well as the most recent advances in the field are presented.Content
1. Dynamics of photoinduced electron transfer. Theoretical models of charge transfer dynamics - Marcus-Hush theory - Fermi golden rule - Semi-classical model - Photoinduced ET - Sensitization of a wide bandgap semiconductor - Detailed treatment of examples of homogeneous and micro-heterogeneous systems
2. Photoelectrochemistry of semiconductors. Contact phenomena at the solid/solid and solid/electrolyte interfaces - Case of finely dispersed semiconductor particles - Ions specific adsorption and surface states - Dynamics of charge carriers in the solid - Spectral sensitization of large bandgap semiconductors
3. Photo-electrochemical conversion of solar energy. Thermodynamic principles and limitations of solar energy conversion efficency - Photogalvanic and photovoltaic cells - Artificial photosynthesis
4. Photocatalysis. Advanced oxidation processes
5. Photographic and xerographic processes. Molecular systems - Photopolymer systems - Electrophotography - Offset printing - Silver photography - Color reproduction
6. Optical data storage. Color theory - High resolution spectroscopy - Optical discs - Holography.
