介孔TiO2作为催化剂降解污水中有机污染物颇有发展前景,目前主要的研究工作是使TiO2的光响应波长由紫外光向可见光发展。系统介绍了TiO2的光催化降解有机污染物的原理及掺杂改性机理,并指出光催化领域现今存在的问题以及发展趋势。
Mesoporous TiO2 as a catalyst for the degradation of organic pollutants in sewage has great prospects for development. At present, the main research work is to make the photo-responsive wavelength of TiO2 develop from ultraviolet to visible light. The principle of TiO2 photocatalytic degradation of organic pollutants and the mechanism of doping modification are systematically introduced. The existing problems and development trends of photocatalysis are also pointed out.
