摘　　要：TiO2光催化氧化法是一种新型的高级氧化法,其反应条件温和、高效且无二次污染．为了提高TiO2的催化性能,催化剂的改性研究已成为目前光催化领域所关注的一个热点．对近年来TiO2光催化剂的改性方法如无机官能团离子的引入、金属离子掺杂、贵金属沉积、半导体复合、光敏化等方面所取得的进展进行了介绍,分析了其改性机理,并对改性技术的发展方向进行了展望．TiO2 photocatalytic oxidation is a new technique of the advanced oxidation, with the characteristics of soft reaction condition , high efficiency and without secondary pollution. To advance the catalytic activity of TiO2, the modification of the catalyst has become a focus in photocatalytic field presently. The modification methods for TiO2 photocatalyst in recent years, such as the introduction of the ion of inorganic functional group, metal ion mixing, noble metal deposition, semiconductor compounding, dyes sensitization, etc. are introduced. Moreover, the modification mechanisms of various methods are analysed, and the future direction of the modification technology is suggested.
