| Abstract: | The influence of crystal structure and surface state of TiO 2 on its photocatalytic activity was introduced in this paper. The recent modifications on the titanium dioxide photocatalyst,including rare metal deposition,metal ion doping,surface sensitization,composite semiconductors,surface acidification and inorganic template synthesis were summarized. The progress in assist-photocatalysis by electrochemistry, microwave and ultrasonic was also discussed. |
