| Abstract: | In this paper, the mechanism of TiO2 photocatalysis technology was described. And then the effect of particle size, defects, crystal structure, crystal morphology and surface modification were introduced. Finally, the application of TiO2 in sewage treatment, sterilization and air purification were summarized, and the methods for promoting the photocatalytic activity of TiO2 were overviewed, including decreasing particle size of TiO2, increasing its defects, changing its crystal morphology, using mixed-phase and surface modification of TiO2. |
