摘要
扩展TiO2催化的响应光谱范围,已成为目前TiO2光催化最具挑战性的课题之一。从TiO2体相掺杂、表面敏化等方面对近年来实现TiO2可见光光催化的途径和方法进行了简要总结。要进一步提高光催化效率还需:深入理解现有TiO2可见光体系的光催化机理;发现更高效的体相掺杂剂和表面敏化剂;设计和控制掺杂剂和表面敏化剂存在形态。
The study on to extend the spectrum response range of TiO2 photocatalysis into visible light region photocatalysis has became one of the most challenging task in the TiO2 photocatalsis field. The recent progress on the methods to realize the visible light response of TiO2 was reviewed briefly in the terms of bulk doping of TiO2, surface sensitization of TiO2, and so on. Future research on this field should be focused on the following questions： deeper understanding on the mechanism of the existing visible photocatalytic systems; exploiting for the more efficient bulk dopant or surface sensibilizer; design control of the existing states of the dopant and surface sensibilizer in TiO2.
