| Research Abstract |
The coverage of metal catalysts with silica layers is an effective method to enhance the stability of catalysts. On the other hand, it brings about the possibility of decrease of activity because the silica coverage could suppress diffusion rate of reactant. In addition, the application could be confined to catalytic reaction associated with small molecules. In this study, we prepared metal catalysts covered with porous and thin silica layers. It was found that the silica-coated metal catalysts had remarkable thermal stability of the metal without major sintering and showed high catalytic activity because the microporous and thin silica layers enable the high diffusion rate.
