| Research Abstract |
Design of integrated heterogeneous catalysts was carried out by utilization of porous siliceous materials with higher-order nanostructure, i.e., hierarchical macroporous networks with mesoporous frameworks. Spherical polymer particles and organic surfactant was used as a hard template for construction of nanostructures. Efficient catalysts for transformation of relatively large molecules were successfully developed by incorporation of transition metal oxide species within their frameworks and loading of Pt nanoparticles on their surface. The comparative studies also revealed that the roles and unique properties of higher-order nanostructure.
