Redox Catalysis in Photochemical and Photoelectrochemical Solar Energy Conversion Systems

  • Chapter
Photoelectrochemistry, Photocatalysis and Photoreactors

Part of the book series: NATO ASI Series ((ASIC,volume 146))

Abstract

Photochemical and photoelectrochemical systems for the generation of fuels using visible light involve invariably two key steps: i) a photoredox system for the generation of strong oxidants and/or reductants and ii) redox catalysts to assist the multi-electron transfer steps leading to the production of H2,O2 and other photoproducts from these intermediates. The present paper is an unifying overview of all such systems using both homogeneous dyes and semiconductors (electrodes, colloids and dispersions) as light absorbers, with emphasis placed on the redox catalysis step. In addition to discussing the general principles of redox catalysis and its applications in the photodecomposition of water into H2 and O2 are also included various mechanistic studies on these by various physical methods: flash photolysis, pulse radiolysis, stopped flow kinetics, electrochemical and photoelectrochemical techniques.
