Abstract: Ni-Cr-Fe ternary alloy membrane electrode was prepared by activation reactive sintering method with Ni powder, Cr powder and disused tinplate as raw material. The phase constitution, morphology and element component were characterized by XRD, SEM, EDS and XPS. The electrocatalytic hydrogen evolution performance of Ni-Cr-Fe alloy electrode was investigated by cyclic voltammetry curve, the linear polarization curve, potentiodynamic polarization curve, and electrochemical impedance spectrum. The results indicated that, at room temperature, hydrogen evolution over-potential of Ni-Fe binary alloy electrode material in 6 mol/L KOH solution was -0.59 V, and the exchange current density is 20.6 mA/cm2, and Tafel slope is 121.3 mV/dec. Under the same condition, the Ni-Cr-Fe ternary alloy membrane electrode exhibits better hydrogen evolution performance. The hydrogen evolution catalytic activity is improved by adjusting the content of Cr. Furthermore, Ni-30wt%Cr-Fe membrane electrode displayed the best hydrogen evolution ability. It′s overpotential for hydrogen evolution is only -0.39 V, the exchange current density is 30.9 mA/cm2, and Tafel slope is 78.1 mV/dec. Through the open circuit potential test, the open circuit potential (η) of the electrode material changed from -0.87 V to -0.69 V after 28 160 s, only increased by 18 mV, which indicating that the electrode has good chemical stability.
