摘　　要：高效光催化剂的设计是光催化研究的关键.本文介绍了超临界处理、醇解、溶剂蒸发诱导自组装(EISA)法和喷雾干燥技术在特定结构TiO2和非钛催化剂制备中的应用,并初步介绍了光催化剂的构效关系,说明具有特定组成和形貌结构的光催化剂的制备对提高光催化性能起到了关键的作用.The keystone of photocatalysis research is the design of highly efficient photocatalysts. This paper describes the applications of supercritical treatment, alcoholysis, evaporation induced self-assembly, and aerogel drying methods in the preparation of various titania and non-titania photocatalysts with tailored structures, The correlation of the catalytic properties to the structural characteristics is discussed briefly, which shows that the unique composition, structure, and morphology play key roles in enhancing the photocatalytic performance.
