Photocatalysis by powdered semiconductors has received much attention from the standpoint of photochemistry of solid surfaces as well as the utilization of solar energy. It seems to be important to clarify the role of surface ions at positions of coordinative unsaturation in photoinduced surface reactions, especially in the primary processes and the excited states of the catalysts. In connection with these problems the authors have recently investigated the photoluminescence of metal oxides as well as making ESR measurements of the transient intermediate species together with analyses of the photoreaction products. In previous papers, the authors have reported that the charge transfer excited state, (Me/sup (n-1)+/-O/sup -/), plays a significant role in photoreactions on supported transition metal oxides; the O/sup -/ species with trapped holes as well as the Me/sup (n-1)+/ ions with trapped electrons are closely associated with the key species of the photoinduced surface reactions. In the present work similar studies have been extended to the photoinduced decomposition of methanol on supported MoO/sub 3/ catalysts. It has been found that the reaction leads to the formation of hydrocarbons similar to those obtained in the methanol conversion reaction on shape-selective zeolite catalysts such as ZSM-5. 14 references
