BiVO4 is an excellent visible-light-driven photocatalyst that can split water into O2 for its more positive valence band than that of O2/H2O, whereas its positive conduction band makes it difficult to directly generate H2 from H2O. But using the PEC, BiVO4 can become a promising candidate as photoanode for hydrogen evolution performance. In our group, the leaf-like structure BiVO4 photoelectrodes were prepared by electrochemical deposition, in which Zn2+ ions were introduced as a direct agent to control the morphology and size of Bi nanoparticles . NiFe2O4 and CoFe2O4 nanoparticles were loading on the surface of BiVO4 to construct heterojunction. The heterojunctions can effectively prevent carriers from recombining and accelerate the separation of electrons and holes . Besides, Bi/ BiVO4  and FeF2/ BiVO4 can enhanced PEC hydrogen evolution performance.
