Titanium dioxide (TiO₂) is regarded as one of the important semiconductor materials for the wide applications in the field of the solar water splitting, sewage disposal and spin electronics and so on. Therefore, doping with proper elements to improve and extend its scope of applications has become the focus of recent research fields. Comparatively speaking, the nonmetal elements can improve the performance of TiO₂ by reducing the band gap, improving the light absorbing capacity, and reducing the electron and hole recombination rates. In this paper, we mainly summarize the change of room temperature ferromagnetism and catalytic performance of TiO₂ doped with nonmetal elements via various preparation techniques. The review may contribute to the further studying and wider application of TiO₂.
