Abstract：

At present, the demand for NH₃ is gradually increasing, and the traditional production process has been difficult to meet the requirements. Doping TiO₂ with single atom can play a better catalytic role and improve the production efficience of NH₃ . In this paper, the use of single atom doped TiO₂ for photocatalytic industrial nitrogen fixation is mainly discussed. Firstly, the unique properties of single atom catalysts are introduced. On this basis, several methods of single atom doped TiO2 for photocatalytic industrial nitrogen fixation are introduced. The mechanization of single atom doped TiO₂ to improve photocatalytic activity is introduced, hoping to provide reference for the production of NH₃ .
