摘要:Large size and high efficient nanoporous BiVO4 photoelectrode was prepared through a simple printing-like electrochemical synthesis method. The prepared BiVO4 electrode was applied to split water to produce O-2 and H-2 in a three-electrode system under the irradiation of simulated solar light. NiOOH as cocatalyst was deposited by photo-electrodeposition method to improve the photoelectrochemical (PEC) performance of BiVO4 photoanode. Results reveal that NiOOH can enhance the photocurrent density and lower the over potential of water oxidation reaction. IPCE measurements were used to evaluate solar energy conversion efficiencies of BiVO4 photoanode and BiVO4/NiOOH photoanode. These two kind electrodes showed 17% and 24% IPCE in water splitting reaction. Furthermore, the prepared large size photoanode was proved to have good stability for water splitting. Our study raises the feasibility of fabrication of large size photoelectrode with high efficiency for practical application.
