Preparation and Application of Electrospun Photocatalysts

Photocatalysis technology could efficiently harness solar energy to drive chemical reactions. The traditional nanoparticle photocatalyst is easy to agglomerate, easy to lose, and difficult to separate and recycle, which has the risk of secondary pollution. However, the electrospun nanofibers are characterized by small fiber diameter, small membrane aperture, large specific surface area, and high porosity, which can be used as the substrate of photocatalyst support and provide more photocatalytic reaction sites. Therefore, this chapter introduces the reaction principle of photocatalysis and the problems faced by photocatalysts. Further, the types and applications of electrospun photocatalysts are also introduced.
