英文摘要: This project aims to prepare the functional composite materials, which are composed of hierarchical porous zeolite as the host and metallic nanoparticles (metal, metal oxide or sulfide and so on) as the guest. Owning to the rigid zeolitic framework, the metallic nanoparticles will be restricted in the domain of mesopores and the morphologies will be well controlled. Through the studying and comparison of the zeolitic framework type, morphologies and porosity of the hierarchical porous zeolites, the loading capacity and distribution of metallic nanoperticles inside the porous host,the catalytic properties of these composite materials will be tested in different catalytic reactions. The different type of metallic nanoparticles will be also investigated in detail in the specific catalytic reactions. We try to find out the general laws between the structural characteristics and catalytic properties,in order to provide a feasible reference and guidance for the preparation and development of novel nano-catalysts。 We aim to develop a series of novel composite materials which possess excellent catalytic properties and devote ourselves to explore their application in practical industrial catalysis.
