摘要
纳米TiO2光催化剂因其较宽的带隙而只能被紫外光激发,探索拓展其光敏感区域至可见光范围,从而使其可见光催化活性具有重要的意义,拓展纳米TiO2光谱响应范围的方法主要包括:金属掺杂、非金属掺杂以及表面光敏化等,对这方面的研究进展进行了简要综述。
Nanostructured titania is activated only under UV light irradiation because of its large band gap.Therefore,it is very significant to explore efficient approaches to extend its response from UV to visible light region,and find visible-light-induced titania photocatalysts.This paper presents a brief review on the progress in research of visible-light-induced nano TiO2 photocatalysts by the modifications of titania which include metal-doped,nonmetal-doped and photosensitization.
