Abstract:

    The unique and fascinating properties of silica-based zeolites and mesoporous silicas have opened up new possibilities for many chemical and physical processes.  Because they are transparent to UV-visible light, silica materials have often been functionalized with elements such as Ti, Cr, V, Mo, and W whose corresponding bulk oxides are known to be suitable photocatalysts. These well-defined active centers have shown to be highly dispersed at the atomic level in a tetrahedral-coordination geometry and have been named as “single-site photocatalysts”. In the case of single-site photocatalysts, excitation by light of Mn+-O2- pairs induces a metal-to-oxygen electron transfer resulting in the formation of an exaction. In this presentation, our recent researches on design of single-site photocatalysts and plasmonic nano-metal catalysts using nano-porous materials have been introduced.
