| Research Abstract |
The present research topics are the template synthesis of novel metal nanoclusters in ordered nano-space of micro/meso materials such as zeolite and mesoporous silica and the innovation of novel molecular transformation by using a concerted effect between the metal nanoclusters and the porous materials. We found the dependence of mesopore diameter of mesoporous silica on the catalytic activity in Pt nanoparticles-catalyzed PROX(Preferential Oxidation)reaction of CO in excess H2. Pt nanoparticles in mesoporous silica with pore diameter of 4.0 nm show the highest catalytic activity than those with other pore diameters. Several mechanistic studies suggest that the mesoporous silica does not simply provide the mesospace but also exhibits concerted catalytic functions with the metal species. We also developed the methods for selective modification of surface silanol groups on mesoporous silica. The mesoporous silica silylated selectively on its external surface was prepared and characterized in detail. After immobilization of Cu species on its internal surface, catalytic application in oxidative polymerization of a phenol derivative was examined.
