摘要
光催化技术是一种新兴的高效节能现代污水处理技术。在参考近年来国内外光催化领域文献资料的基础上,综述了金属离子修饰TiO2技术研究新进展。从离子修饰机理角度解释了离子修饰提高TiO2光催化活性的原因,进一步阐述光催化技术面临问题及发展前景。
Photocatalytic process is one of the current technology with high efficiency and economizing energy for the removal of pollutant from water.Recent progress of modifications of TiO2 doped by transition metal ions has been summarized,based on the findings reported in the present literatures.The cause which ion doping improves photocatalytic activity of TiO2 has been exlained according to the mechanism of ion modification,and problems and prospects of photocatalytic process are analyzed.
