The characteristics of photogenerated charge can be improved by regulating the microstructure of monoclinic bismuth vanadate (mBiVO4),and consequently enhanced its photocatalytic activity.The nanostructure of mBiVO4 material can be able to accelerate the electron migration rate as well as promoted the separation efficiency of photogenerated charge.The special morphology can shorten the migration path of photogenerated charge which was advantageous to the separation of photogenerated charge to the surface,and then facilitated the photocatalytic reaction of surface active sites.The research process of the three-dimensional (3D) nanostructured mBiVO4 photocatalytic materials with different morphologies,such as peanut-like,olive-like,flower-like,dendrite,and other shapes in the field of photocatalytsis were described,and looked forward to the future development of this kind of photocatalysis material.
