| Research Abstract |
In the vapor phase selective photocatalytic oxidation of alkanes, alkali-ion-modified silica-supported vanadium oxide was found to be appropriate catalyst system while in the liquid phase selective photocatalytic oxidation, alumina-supported vanadium oxide was found to be suitable. The general mechanism of photocatalytic oxidation of alkanes was proposed. In the liquid phase selective photocatalytic oxidation of alcohols, niobium oxide itself was found to be the best and its reaction mechanism was proposed. Although low-loaded vanadium oxide supported on silica was known to be effective for photo-epoxidation of propene with molecular oxygen, the active species is now under discussion. New photocatalytic system with porphyrin complex was developed for liquid phase photocatalytic oxidation of alkenes. Photoexcited mechanism of surface vanadium oxide species was clarified by both experimental and theoretical investigations.
