TiO_2光催化活性向可见光区拓展的研究进展

Research progress of the activity of the photocatalyst TiO_2 driven from the ultra-violet region to the visible region

TiO2光催化剂可用于光分解有机污染物,组装太阳能电池,光分解水制氢气或氧气等领域。本文对可见光响应的TiO2光催化剂国内外研究进行了综述,概述了采用敏化,掺杂等方法可使二氧化钛光催化活性从紫外光区拓展到可见光区,并对未来的研究方向进行了展望。

TiO2 photocatalyst has been used for decomposing organic pollutions, constructing solar cells, splitting water into hydrogen or oxygen by solar energy . In present paper , recent observations progress about photocatalyst TiO2, which responds to visible light were reviewed. Several methods were introduced using sensitizers or dopants to drive the reactivity of the photocatalyst TiO2 under ultra-violet light to visible light and the research direction in the near future has also been previewed.
