摘　　要：TiO2以其催化活性高,热稳定性好,抗光氧化性强及无二次污染等特性成为最受重视的一种光催化剂。本文介绍了TiO2光催化机理、指出了TiO2的缺点,重点对TiO2光催化剂的改性、提高其降解废水效率的研究进行了综述,提出了今后TiO2光催化剂改性的研究方向。For the high catalytic activity, good heat stability, strong resistance of photo oxidizability and no secondary pollution and other merit, the TiO2 photocatalyst is the more setted store by reseachers. TiO2 photocatalysis mechanism, modification of TiO2 photocatalyst and its improving the efficiency in degradation of waste water were summarized in this thesis. At the same time, the weakness of TiO2 photocatalyst was pointed out too. Finally, the development of the research direction on modification of TiO2 photocatalyst was indicated.
