摘　　要：大比表面积、高孔隙率的介孔金属氧化物具有特殊的光、电、磁、催化等性能,引起密切关注。本文综述了介孔金属氧化物的模板法合成机制及该类材料在催化、电化学、制备新材料等方面的最新研究进展;介绍了软、硬模板法合成机理及产物结晶理论;着重阐述了硬模板法中模板性质、前驱物与介孔孔壁作用力、前驱物的聚集和迁移、实验条件等因素对产物结构的影响;最后,对该类材料的未来发展进行了展望。Mesoporous metal oxides with large specific surface area and high porosity have attracted an increasing interest due to its special optical, electrical, magnetic, catalytic properties etc. In this paper, we reviewe the latest researches on the template synthesis mechanism of the material and their applications in catalysis, electrochemistry, fabricating new materials. The mechanisms as well as the crystalline theories for both the soft and hard template systhesis route are described in detail. Besides, we focus on the factors that are closely related to the structure of the target compound during the hard-template process, including the properties of the template, the interactions between the precursor and the pore wall of the template, the aggregation and migration of the precursor, the experiment conditions and so on. Finally, the developing prospects in this area are provided.
