TiO2表面亲水性高灵敏度化的研究进展

Progress in High Sensitization of Hydrophilicity of the Surface of TiO2

简述了TiO2表面产生光诱导亲水性的机理，在此基础上介绍了利用桥氧和改变TiO2表面的纳米结构尽可能地引入拉伸应力并防止压缩应力的产生，以及利用氧化钨和氧化钛两种光触媒复合等途径，有效地提高其超亲水性特性，使之能在1μW／cm^2的弱光下得以应用。

This paper reviewes the mechanism of the hydrophilicity-sensitization of the surface of TiO2 ; dis cusses the methods which can improve effectively the hydrophilicity such as the introduction of the bridging-oxygen bonds, changing the microstructure and morphology of the surface of TiO2, introducing the stretched stress as much as possible and at the same time avoiding compressed stress, and the complexity of the different photo-catalytic agents like tungsten oxide and titanium dioxide, analyzes the application prospect of these new materials under the light intensity of 1μW/cm^2.
