However, its relatively poor charge transport property and wide bandgap are two main limitations for its extensive application in light-responsive materials. To meet such challenges, two strategies including ion doping and going nanoscale are used and demonstrated to be effective in regulating its band gap structure and charge transport behavior. Ion doping can be divided into two categories, metal doping and nonmetal doping, according to the properties of the impurity elements. Besides, compared with traditional titanium dioxide, nano-sized titanium dioxide possesses larger surface areas and special nanosized effect, resulting in higher chemical activity and heat resistance. In this review, we focused on the research progress of non-metallic element doped titanium dioxide. Emphases was put on the relationship within the doping element, the band gap structure, visible light responsibility and photocatalytic performance of the hybrid titanium dioxide. Additionally, the application of non-metallic element doped titanium dioxide was also involved. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
