摘  要:利用卟啉类化合物敏化TiO_2,使复合催化剂克服TiO_2原有的光响应局限,抑制光电子-空穴的复合、增强光催化降解性能已成为研究热点。介绍了卟啉类衍生物对TiO_2的敏化机理,综述了卟啉敏化TiO_2在降解有机物领域的最新研究进展,总结了影响敏化效果的几种主要因素。指出未来卟啉敏化TiO_2光降解催化剂发展的研究重点是通过加强卟啉类敏化剂与TiO_2的相互作用,尤其是键合作用,制备出性能稳定、价格低廉的催化剂。Porphyrins are used to help composite catalysts to overcome the original photoresponsive limitations of TiO2,suppress recombination of photoexcited electron-hole pairs and improve the photocatalytic degradation performance,which has become a hot topic.This paper presents a comprehensive introduction of the mechanism of sensitization of TiO2 by porphyrin derivatives,the latest research progress in organic degradation by porphyrin sensitized TiO2,and several main factors affecting the photocatalytic performance of porphyrin sensitized TiO2.Finally,it is pointed out that the research on future development of the photolysis catalyst(porphyrin-sensitized TiO2)should be focused on the preparation of stable and low-cost catalysts by strengthening the interaction of porphyrin-based sensitizers with TiO2,especially the bonding effects.
