纳米TiO_2光生超亲水性研究进展

Research Progress of Photoinduced Superhydrophilicity of Nanometer TiO_2

纳米TiO2作为光催化环境材料能有效地降解多种对环境有害的污染物,使有害物矿化为CO2、H2O及其他无机小分子物质,因此可用于废水处理,空气净化以及杀菌除臭。本文综述了纳米级TiO2的制备及其光生超亲水性的机理,扼要介绍了纳米级TiO2光生超亲水性在自清洁建材、杀菌消毒等方面的研究进展及应用前景。

As a photocatalysis environmental material, nanometer TiO_2 can effectively degrade pollutants, and mineralize them to CO_2, H_2O and other inorganic small molecule substances. So nanometer TiO_2 can be applied to wastewater treatment, air cleaning , sterilization and deodorization. In this paper, a review is given on its preparation and photoinduced superhydrophilicity mechanism of nanometer TiO_2 , and the research progress and application prospect of nanometer TiO_2 in self cleaning building materials and sterilization etc.
