摘要
纳米 Ti O2 作为光催化环境材料能有效降解多种有害的污染物 ,使有害物质矿化为 CO2 、H2 O及其他无机小分子物质 ,因此光催化降解水中有机污染物是一项新兴的颇有发展前途的废水处理技术。综述了纳米Ti O2 的制备、光催化降解水中有机污染物的机理。
Since the nano TiO 2, as a photocatalyst, can effectively degrade pollutants which are harmful to the environment and can mineralize the harmful pollutants to CO 2, H 2O and other small molecules, the photocatalytic degradation of organic contaminant is considered as an emerging while promising technology for waste water treatment. The preparation of nanosized TiO 2, the mechanism, kinetics principle, current research situation and development tendency of photocatalytic degradation of organic contaminant in waste water were all described. The improvement of nano TiO 2 photocatalyst was also introduced.
