摘要：

A strategy is proposed for modifying BiVO(4)photoanode with CoNiO(2)as a novel water oxidation cocatalyst to enhance PEC water splitting performance. The results show that CoNiO(2)has the following functions: reducing photogenerated charge recombination centers; providing trapping sites to promote charge separation; improving the stability of the overall system; providing more active sites; and offering a lower overpotential. The BiVO4/CoNiO(2)photoanode has a higher photocurrent density (1.16 mA cm(-2)at 1.23 Vvs.RHE), a lower onset potential (similar to 0.06 Vvs.RHE), a larger IPCE (34.37%) and ABPE (0.163%), better stability and good rates of hydrogen evolution (0.0148 mu mol cm(-2)min(-1)) and oxygen evolution (0.0076 mu mol cm(-2)min(-1)). The strategy provides promising prospects for achieving efficient PEC water splitting performance using water oxidation cocatalysts.
