Abstract 

Finding low-cost and efficient electrocatalysts towards hydrogen evolution reaction (HER) is a crucial step towards a sustainable "hydrogen economy". In this paper, MoS2-Ni2P/reduced graphene oxide (RGO) has been prepared by a solvothermal reaction. The MoS2-Ni2P/RGO composite exhibits high HER activity in the acidic media, with overpotentials of 160 mV at the current density of 10 mA·cm-2 and a low Tafel slope of 35.9 mV·dec-1. The synergistic effect of the combination of Ni2P and MoS2 is attributed to hydrogen spillover from Ni2P to MoS2.
