| Abstract: | Non-precious metal electrocatalyst molybdenum sulphide(MoS) and black phosphorus(BP) are highly promising catalysts for H_2 evolution reaction(HER).However,BP is environmentally unstable and the basal planes of crystal MoS_2 are inactive toward HER.Herein,amorphous molybdenum sulphide(MoS_x)directly on BP/BiVO_4 film dramatically improves the performance of photoelectrochemical water splitting compared with pure BiVO_4.Additionally,we demonstrate that a BP layer,inserted between the MoS_x and BiVO_4,can enhance the photoelectrochemical performance and improve the stability of the electrodes.Finally,MoS_x/B P/BVO electrode shows the excellent current density of 2.1 mA/cm~2 at the potential of 1.2 V(vs Ag/AgCl),which is twice higher than that of pure BVO electrode.Our novel nanostructure materials will lead to a new class of non-precious metal photocatalysts for hydrogen production. |
