It is of great practical significance to design and develop low-cost and high activity hydrogen evolution electrocatalysts in the all-pH (0~14) range for the development and utilization of new energy. Nanowire structured MoS2/Ni3S2/NF electrocatalysts were in situ constructed on nickel mesh (NF) by a simple solvothermal method, which exhibited excellent hydrogen evolution (HER) activity in the all-pH range. The electrochemical test results show that the MoS2/Ni3S2/NF-41 electrode prepared with 41 mg ammonium tetrathiomolybdate has a HER overpotential of 87, 113 and 195 mV in alkaline (1 moL/L KOH, pH=14), neutral (0.5 moL/L PBS, pH=7) and acidic (0.5 moL/L H2SO4, pH=0) media at a current density of 10 mA/cm2, and exhibits a lower Tafel slope. In addition, SEM, TEM, EDX, XPS and other characterization methods show that the catalyst has good structural stability. This study provides a new way for efficient hydrogen evolution of transition metal sulfides in a all-pH environment.
