The amorphous Ni-Mo-Co alloy electrodes were prepared by electro-deposition. The properties of three electrodes different in molar ratio content of Ni²⁺, Co²⁺ and Mo⁶⁺ were compared at pH=9.5 and 40~50℃. Their morphology, element composition and crystal structure were evaluated by SEM, EDAX and XRD analyses. The electrodeposited alloys are amorpohous, silver bright and compact. The catalytic property of the alloy electrodes in hydrogen evolution reaction in 1 mol/L NaOH solution was studied by linear sweep voltammetry and ac impedence measurement. The electrodes have lower overpotential and better catalytic property than pure Ni electrode.
