摘要：

Development of cathode material which has low HER (hydrogen evolution reaction) overpotential and high durability is significant to electrolysis industry and antifouling with electrolyzing seawater. The amorphous Ni-S alloy electrode was prepared by means of electrodeposition. Its electrocatalytic activity and stability for HER in 5 mol/L NaOH solution at 353 K was investigated. The result showed that the amorphous Ni-S alloy in which sulphur content is 29.4%, has high electrocatalytic activity and excellent stability. In addition, the morphology and phase structure of the NiSx alloy electrode before and after electrolysis were studied by SEM (scanning electron microscope) and XRD (X-ray diffraction).
