Abstract
Amorphous Ni/Fe/Mo alloys were obtained by electrodeposition from an alkaline citrate bath. The effect of the cathodic current density on the chemical composition, surface morphology of the Ni/Fe/Mo alloys, and the current efficiency of the deposition process was determined. The activity of the Ni/Fe/Mo alloy for the hydrogen evolution reaction (HER) was investigated under various electrolysis conditions in 30 wt.% KOH at 70 °C. The results showed that the Ni 41.49Fe 23.02Mo 35.49 alloy had the best activity for HER and excellent stability under continuous electrolysis. When accompanied by some current interruptions of various durations, the ternary alloy electrode still maintained good activity for HER.
