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.

利用具有高阶纳米结构的多孔硅质材料（即具有介孔骨架的分级大孔网络）进行集成非均相催化剂的设计。球形聚合物颗粒和有机表面活性剂被用作构建纳米结构的硬模板。通过在其框架内掺入过渡金属氧化物物质并在其表面负载 Pt 纳米颗粒，成功开发了用于转化相对较大分子的高效催化剂。比较研究还揭示了高阶纳米结构的作用和独特性质。
