摘要
本文综述了近几年来复合TiO2光催化剂的发展现状。分别从分类、制备方法及光催化性能三方面进行系统论述。根据复合的物质不同,将复合TiO2光催化剂分为金属掺杂型、非金属掺杂型和半导体复合型。概述了溶胶-凝胶法、水热法、浸渍法等常用于复合TiO2光催化剂的制备方法以及复合TiO2光催化剂在降解水体有机污染物、分解水制氢、空气净化等方面的应用。
This paper summarizes the developmental situations of the composite TiO2 photocatalyst in recent years, and elaboratos on three aspects of classification, preparation method ＇and photocatalytic. Performance the different composites, the composite TiO2 photocatalyst can be classified into three categories of metal - doped, non - metal - doped and semiconductor - compound. On the preparation of the composite TiO2 photocatalyst, sol - gel methods, hydro - thermal method, dipping method, and so on are adopted. In addition, this paper also sums up the application of the composite TiO2photocatalyst on the degrading the inorganic pollutant in the water environment, photocatalytic H2 - splitting water, and air purification, and so on.
