氮掺杂可拓宽TiO2的光响应范围和实现可见光响应、增强其对太阳光能的利用和提高它的光催化效率而成为该领域关注的焦点。本文综述了氮掺杂对TiO2能带结构的影响及氮掺杂纳米TiO2薄膜和粉体的制备方法等方面的研究进展,总结了该领域研究中亟待解决的问题并对今后的发展提出了作者的思考。

Nitrogen doped TiO2 has attracted much attention as nitrogen doping can widen its photo re- sponse range, realize its visible light response, improve the utilization of solar light energy and further increase its photocatalytic efficiency. The effect of nitrogen doping on the band structure in the TiO2 and the research progress on the preparation method of nitrogen doped TiO2 film and powder were re- viewed. The current problems needed to be solved were summarized, and some thinking on the future development was also put forward.
