Abstract : Sensitized interfacial photoreactivity has been investigated as a means for accomplishing unique chemical transformations. Photoreactions on heteropolyoxoanions, on clays on native and modified form, and on zeolites of varying size, selectivity and catalyst loadings have been examined. An array of reactions which occur with substantially different reaction pathways or do not occur at all in conventional homogenous solutions has been investigated. These include novel oxidative and/or reductive cleavages of organic substrates. Both mechanistic and synthetic studies of multi-functional molecules have been conducted. Keywords: Photocatalysis; semiconductor surfaces.
