新型可见光响应光催化剂的研究进展

Advances in Novel Photocatalysts under Visible-light

研究开发高活性的可见光响应催化剂对于解决环境污染和能源短缺问题具有重要意义。在阐述反应机理的基础上,介绍了改性Ti O2、多元金属复合氧化物、卤氧化物、铋系化合物等新型可见光响应光催化剂的研究现状,并对未来可见光响应催化剂的机理探讨、催化活性提高、制备新技术等方面的研究进行了展望。

It is very significan t to develop highly active photocatalysts under visible-light for solving the energy crisis and environmental problems. Based on the reaction mechanism, recent progress of novel photocatalysts under visible-light, such as modification of TiO2, multiple metal composite oxide, halogen oxide, bismuth compounds were introduced. The promising research trends of novel photocatalysts under visible-light had been prospected from three aspects：photocatalytic reaction mechanism, photocatalytic activity and preparation method.
