Oxygen Activation and Photoelectrochemical Oxidation on Oxide Surfaces
Abstract
Water oxidation catalysis by polypyridyl complexes of Ru(II) has been investigated mechanistically including studies in nonaqueous solvents with exploitation in electrocatalysis. Electrocatalysis studies have been extended to CO2 reduction to CO and, with added weak acids, to syngas (H2:CO) production and to CO2 splitting into CO and O2 based on a single catalyst. The reduction chemistry has been similarly extended to H2 production in a dye sensitized photoelectrosynthesis cell (DSPEC). Studies on DSPECs have been extended to the demonstration of accumulated multiple oxidative equivalents at surface catalysts on mesoporous TiO2 and to the exploration of the influence of Li+ doping. A new approach to surface-based assemblies based on phosphonate-derivatized porphyrins has been developed for creating antenna and chromophore-catalyst assembly structures by a layer-by-layer technique.
