摘　　要：纳米TiO2作为光催化环境材料,能有效降解多种有害的污染物,使有害物质转化为CO2、H2O及其他无机小分子物质。本文从TiO2的光催化降解机理入手,介绍了纳米TiO2光催化剂的性能特点,列举了纳米TiO2光催化降解在环保方面的应用,提出环保领域中应用研究现状、存在问题及其解决途径。The photo catalytic mechanism and characterize of man-sized TiO2 in degrading organic and inorganic contaminants were discussed in this paper. The present status and the main problems of its application in the field of environment protection were reviewed. At present, the man-sized TiO2 is of excellent photo catalytic effect only excited by ultraviolet-ray, so that its application was limited. Thus, Looking for a new method to reduce this high-excited energy is the key to amplify its applications field.
