摘要
光催化剂的中毒已经成为限制光催化技术进一步发展的主要因素。对气-固光催化技术和液-固光催化技术中光催化剂失活机制进行了分析,对光催化剂的活性分析技术进行了介绍,并总结了国内外关于TiO2光催化剂中毒再生技术的研究成果,为光催化技术在实际应用中遇到的中毒及再生问题提供了参考。最后,对光催化剂失活的研究进行了展望。
The deactivation of photocatalyst had been the most bafflement during the application of photocatalytic Technology.In this paper,the mechanism for photocatalytic deactivation in gas-solid photocatalytic and liquid-solid photocatalytic reactions,the technologies for analyzing the activity of photocatalysts are introduced,and the studies on the deactivation and regeneration of titanium dioxide photocatalyst in environmental pollution control at home and abroad in recent years were summarized,which give some reference for deactivation and regeneration during the application of photocatalysts.At last,the trends of deactivation of photocatalyst are prospected.
