| Abstract: | In this paper, the principles and characteristics of the preparation of porous oxides by coprecipitation method, sol-gel method, impregnation method and hydrothermal synthesis method were briefly introduced, As a material with special structure composed of different channels, porous materials have the characteristics of large specific surface area, high strength, porosity and adjustable pore size that ordinary materials do not have. Using different preparation methods, porous metal oxides with different morphologies or different channel structures can be obtained. Such oxides have a leading position in the field of catalysis and adsorption with excellent chemical stability and thermal stability, Therefore, it is of great significance to study its preparation methods. The principle and characteristics of soft template method and hard template method for preparing porous oxide are compared in detail. Taking the common soft and hard template as an example, the application of oxide prepared by template method in various fields is summarized. The characteristics of plant template method and the application of porous oxides prepared with plants as templates in adsorption and catalysis in recent years were summarized, and the research direction of porous oxides prepared by this method was prospected. |
