Research Abstract |
Efficient and selective photocatalytic reactions have been achieved with the photocatalysts prepared by the surface modifications. We clarified that the photocatalytic reactions, which depends on the size and polarity of the molecules, proceed on the porous materials containing photocatalytic active site within the pore. In addition, silica catalyst containing Cr-oxide species on the surface successfully promotes partial oxidation of cycloalkanes with molecular oxygen under irradiation of visible light. Furthermore, titanium dioxide loading platinum nanoparticles promotes efficient production of benzimidazoles with alcohols and diamines as resources, under UV irradiation. The present works clarified that surface-modified photocatalysts promote several reactions, which have been recognized to be significantly difficult.
