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。本文在参考近年来国内外光催化领域文献资料的基础上,综述了过渡金属离子修饰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的问题及发展前景。
Photocatalytic process is one of the current technology with high efficiency and economizing energy for the removal of pollutant from water.Recent progress on modifications of TiO_2 doped by transition metal ions has been summarized,based on the findings reported in the present literatures.The cause which ions doped in TiO_2 improve photocatalytic activity of TiO_2 has been exlained according to the mechanism of ion modification,and being faced with problems and developing prospects of photocatalytic process are set forth.
