Ni-Mo-C alloy electrode material was prepared on pure copper by electroplating.Linear sweep voltammetry（LSV）,cyclic voltammetry curve（CV） and electrochemical impedance spectroscopy（EIS） were used to investigate reaction mechanism of hydrogen evolution in 1 mol/L NaOH solution.The results show that hydrogen evolution reaction（HER） is a two-step reaction including adsorption and desorption of Hads and HER is irreversible and controlled by the rate of the mass transfer.Carbon can inhibit the adsorption of Hads,enhance desorption property of electrode for Hads and improve the HER property.Mo has hydrogen desorption synergistic effect with Ni when potential is high,which will enhance the property of HER.
