摘　　要：在参考近两年国内外大量文献基础上 ,对纳米TiO2 的光催化机理、催化剂性能的改进方法和影响催化剂性能的环境因素进行了评述和探讨 ;介绍了催化剂表面声光能辐射处理以及电场、微波、超声波助催化技术等新型增效、助效技术的研究进展 ;并综述了最近两年纳米TiO2 在水环境污染物去除。Based on the newest papers about nano-TiO2, the mechanisms of photocatalysis, ways of improving photocatalytic performance, and influencing factors of environment are discussed in this article. And the progresses in the study on some novel catalysis-enhanced or catalysis-assisted technologies such as infrared treatment, electric field effect, microwave effect and ultrasonic effect are introduced. Finally, the applications to waste water treatment, air refreshment in limited space and specially functional materials preparation in the last two years are reviewed.
