| Abstract: | Metals in the marine environment encounter serious corrosion problems; thus, measures must be taken to protect them. Photochemical cathodic protection is a new green and environmental anti-corrosion technology, which has attracted considerable attention. This study briefly describes the principle of photochemical cathodic protection technology and the requirements for photoanode. Several common photoanode materials represented by TiO2 and their different modification methods are introduced in detail. In addition, the photoanode with the functions of energy storage and cathodic protection, which is expected to achieve the goal of continuous protection in the unilluminated state, is introduced. Finally, the development trend of photoelectrochemical cathodic protection technology is discussed. |
