ELECTRODE PROPERTIES OF AMORPHOUS NICKEL-IRON-MOLYBDENUM ALLOY AS A HYDROGEN ELECTROCATALYST IN ALKALINE-SOLUTION

Amorphous Ni/Fe/Mo alloys were obtained by electrodeposition from an a lkaline citrate bath. The effect of the cathodic current density on th e 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 (HE R) was investigated under various electrolysis conditions in 30 wt.% K OH at 70 degrees C. The results showed that the Ni41.49Fe23.02Mo35.49 alloy had the best activity for HER and excellent stability under cont inuous electrolysis. When accompanied by some current interruptions of various durations, the ternary alloy electrode still maintained good activity for HER.
