| Recently, photogenerated cathodic protection, as one of new electrochemical protection methods, has become a research focus in the field of corrosion protection. TiO2 film has outstanding advantages among photogenerated cathodic protection technologies due to excellent electron-hole separating power, good stability, low cost, etc. Photogenerated cathodic protection principle of the TiO2 film was first introduced, and later various preparation methods of the TiO2 film material including sol-gel, anodic oxidation etching, hydrothermal method, thermal decomposition, electrophoretic deposition and magnetron sputtering were presented. For existing problems of the TiO2 film material, different doping/composite modification approaches were illustrated, covering metal/non-metal doping, surface metal deposition, carbon nanomaterial composite and semiconductor composite. Meanwhile, research progress of photogenerated cathodic protection of different TiO2/metal systems was summarized. At last, the outlook was presented for future development of TiO2 photogenerated cathodic protection technology. Major future development trends of photogenerated cathodic protection technology were proposed to be widening light absorption range of TiO2 film, improving electron-hole separation efficiency, and developing high-binding, wear-resistant and aging-resistant TiO2 coating. |
