摘　　要：随着对半导体纳米TiO2研究的深入,其光催化特性及应用备受关注。在环保中,纳米TiO2常用于污染物的分解,是一种高效无二次污染的光催化剂。文章简要评述了纳米TiO2的基本性质和主要制备方法,探讨了其光催化机理以及在治污中的应用,对纳米TiO2光催化中存在的问题,提出了初步的解决方法。With the study of semiconducting nanoscale TiO2 moving forward, its photocatalytic properties and application have been paid close attention. In environmental protection, nanoscale TiO2 is always used as an efficient photocatalyst to decompose pollutant without secondary pollution. In this paper, the basic properties and main preparation methods of nanoseale TiO2 are reviewed briefly. It mainly concentrates on the analysis of the photocatalytic mechanism of nanoscale TiO2 as well as its applications in pollution control. And some elementary solutions to the current existing problems in photocatalysis of nanoscale TiO2 are also proposed.
