摘　　要：通过在电镀过程实现P体相掺杂制备P-BiVO_(4)光阳极,P-BiVO_(4)光阳极的起始电位相比于BiVO_(4)光阳极发生明显的阴极位移。在光电化学分解水反应中,P-BiVO_(4)表现出高效的选择性和活性。EIS和UPS测试结果表明,P掺杂能够显著加快光阳极的电荷转移,加速BiVO_(4)光阳极载流子的分离,从而延长了空穴寿命和促使空穴向表面转移,能够有效地提升光电化学分解水的OER动力学。P-BiVO_(4) photoanode is prepared through P-phase doping during electroplating.The initial potential of P-BiVO_(4) photoanode shifts significantly compared with that of BiVO_(4) photoanode.P-BiVO_(4) exhibits high selectivity and activity in the photoelectrochemical water-splitting reaction.EIS and UPS tests indicate that P doping can significantly accelerate the charge transfer and carrier separation of BiVO_(4) photoanode,thus extending the hole life and promoting the hole transfer to the surface,and effectively improving the OER kinetics of photoelectrochemical water-splitting.
