摘　　要：综述了近年来尖晶石型金属氧化物超微粉体光催化性能的一些最新研究进展。主要介绍了能够得到较小纳米粒子的合成方法,如:微乳-沉淀法、研磨固相反应法和微波辐射技术、水热法、硬脂酸法、共沉淀法、铝单醇盐溶胶凝胶法、聚合物配位法等制备方法。重点讨论了其在降解甲基蓝、甲基橙染料,苯、甲醛有机污染物及分解水等方面的光催化性能。从不同角度对尖晶石型氧化物光催化机理进行解释,并介绍了目前被广泛认可的几种光催化机理。The resent research progress in photocatalytic performance of the spinel type composite metal oxides nano - powder was reviewed. The synthetic methods of small nano - particle were introduced, such as microemulsion precipitation method, solid state reaction under microwave irradiation, hydrothermal synthesis method, stearic acid gel method, coprecipitation method, aluminium semi - alkoxide sol - gel synthesis, coordination of polymer method, etc. A discussion on photocatalytic performance in photocatalysis degradation of methyl blue, methyl orange dyestuff, benzene, formaldehyde organic contaminators and decomposing water was given. Photocatalytic principles of spinel type composite oxides were explained from different aspects. Moreover, several widely recognized photocatalytic principles were introduced.
