摘要
The traditional nano-powder photocatalyst is prone to agglomerate during use, easy to be drained away and difficult to separate and recover, further causing secondary pollution. Photocatalysis is an advanced oxidation technology that can efficiently use solar energy to degrade pollutants, and is environmental friendly. This paper briefly introduced the research progress and existing problems of the single-component electrospun nanofiber-based photocatalyst. Then on the basis of the existing problems, the methods for enhanced modification the performance of the electrospun nanofiber-based photocatalyst were summarized, including element doping, surface precious metal deposition, semiconductor recombination, dye sensitization and graft conjugated polymers. The synthesis methods, principles, advantages, disadvantages and improvement directions of various methods were summarized. It is proposed that further research should be carried out in the development of new photocatalytic materials with high specific surface area and high electron hole separation efficiency, as well as new photocatalysts with multi-functional synergy and high mechanical strength.
