二氧化钛光生阴极保护材料以自身独特的光电特性直接将太阳光转化为电子,降低金属的电势,为金属提供保护,而自身没有消耗,是一种理想的新型阴极保护材料。本文回顾了近年来国内外二氧化钛光生阴极保护材料的发展,重点介绍了纳米二氧化钛的制备和改性方法以及在提高光生阴极保护性能方面的研究工作,探讨了纳米二氧化钛材料的光生阴极保护机理,并对光生阴极保护材料的发展前景进行了展望。
Titanium dioxide photogenerated cathodic protection material with its own unique photoelectric properties of sunlight directly into electrons, reducing the potential of the metal to provide protection for the metal, but their own consumption, is an ideal new cathodic protection material. In this paper, the development of photocatalytic cathodic protection of titanium dioxide photocatalysts at home and abroad in recent years is reviewed. The preparation and modification of nanometer titania and the research on improving photocathode cathodic protection are reviewed. The photocathode cathodic protection mechanism is also discussed. The prospects for the development of photocathode materials are prospected.
