英文摘要	Nano-porous Ni and nano-porous Ni3S2/Ni composite electrodes were prepared by dealloying and hydrothermal synthesis. The pore size distribution, phase and microstructure of the electrode were characterized by N-2 adsorption-desorption test, XRD, SEM, TEM. In 1 mol . L-1 NaOH solution, the electrocatalytic properties toward hydrogen evolution reaction of the electrode was evaluated using linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS) and constant current electrolysis method. As a result, when the current density was 50 mA . cm(-2), the nano-porous Ni3S2 composite electrode had a lower overpotential for hydrogen evolution reaction and higher electrocatalytic hydrogen evolution activity than the nano-porous Ni, while nano-porous Ni3S2/Ni composite electrode had lower apparent activation energy and electron transfer resistance, it further clarifies the special contribution of transition metal sulfides to the performance of electrocatalytic hydrogen evolution.
