摘　　要：印染工业的发展加剧了环境污染,传统的处理染料废水的方法存在许多难以克服的缺点。从保护环境和节省能源的角度出发,人们对TiO2应用在染料污水降解领域的研究给予了较大的关注。本文从TiO2的催化机理,降解方式,负载方式以及可降解的染料种类等方面进行了归纳,指出了目前TiO2在降解有机染料方面的一些不足,并对其发展方向进行了预测。Dyestuffs from the textile industries are becoming a major source ofenvironmental contaminations. The treatment of dye-containing wastewater by conventional methods has drawback due to difficulties in the complete removal of color and expensive. From the viewpoint of protecting environment and saving energy, people have a good attention to the researches about using TiO2 degradation the dyestuffs waste water. This paper reviews the current status of research on the catalysis mechanics, degradation mode, loading mode of TiO2 and the variety of the dyestuffs that could be degraded by TiO2, Some problems existing in present and the development tendency in the field are proposed.
