Abstract

Non-precious metal electrocatalyst molybdenum sulphide (MoS) and black phosphorus (BP) are highly promising catalysts for H2 evolution reaction (HER).However,BP is environmentally unstable and the basal planes of crystal MoS2 are inactive toward HER.Herein,amorphous molybdenum sulphide (MoSx) directly on BP/BiVO4 film dramatically improves the performance of photoelectrochemical water splitting compared with pure BiVO4.Additionally,we demonstrate that a BP layer,inserted between the MoSx and BiVO4,can enhance the photoelectrochemical performance and improve the stability of the electrodes.Finally,MoSx/BP/BVO electrode shows the excellent current density of 2.1 mA/cm2 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.
