Abstract
Both direct spectroscopic observation of intermediates formed on irradiated semiconductor surfaces and product analysis from inter- and intramolecular competition experiments with multifunctional organic substrates implicate direct interfacial electron transfer from an adsorbed organic donor as a primary process in photocatalytic oxidation reactions. Time-resolved diffuse reflectance spectroscopy is used to measure kinetic profiles for the decay of photogenerated transients on opaque, photocatalytically active metal oxide powders. The implications of such studies in the mechanistic characterization of photocatalytic detoxification are considered.
