摘要 介绍了TiO2多相光催化降解有机污染物影响因素的最新研究进展,及pH、外加剂等对TiO2多相光催化降解的影响。在高pH溶液中,能产生较多的·OH,即使TiO2和污染物静电引力较弱,仍可能具有较强的光催化降解性能。特别指出,TiO2多相光催化技术不适合处理浓度较大的有机废水,但对浓度低、毒性强的新兴污染物处理呈现良好的应用前景。

Abstract: This paper introduces the latest research progress on the factors affecting the heterogeneous photocatalytic degradation of organic pollutants over TiO2 and the effects of pH,additives and other factors on the heterogeneous photocatalytic degradation over TiO2.More ·OH can be generated in a solution with a higher pH,therefore the catalyst will exhibit stronger photocatalytic degradation performance even if the electrostatic attraction between TiO2 and pollutants is weaker.Particularly,the TiO2 heterogeneous photocatalytic technology is not suitable for treating with high concentration organic wastewater,but has potential development in treatment of emerging contaminants with low concentration and high toxicity.
Key words:  titanium dioxide    heterogeneous photocatalytic    degradation    organic pollutants
