 Abstract

            Using the electrodeposition method, this study investigates the efficacy of an alloy based on nickel and molybdenum as an electrode in water splitting applications. A copper substrate with a current density (c.d.) between 1.00 and 4.00 A dm^-2 was coated with nanocrystalline nickel-molybdenum alloy, and the deposit properties and electrocatalytic behavior in a 1.00 M KOH solution were examined. The electrocatalytic behavior of the coatings in relation to their oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) was assessed using electrochemical methods including cyclic voltammetry (CV) and chronopotentiometry (CP). According to the experimental results, the maximum electrocatalytic potential for HER and OER is found in nickel-molybdenum alloys electrodeposited at 1.00 A dm^-2 (38.30 wt% of molybdenum) and 4.00 A dm^-2 (33.20 wt% of molybdenum). When compared to other coatings, nickel-molybdenum alloys coated at 4.00 A dm^-2 exhibit the greatest corrosion resistance in an alkaline medium. According to SEM and XRD, the greatest electrocatalytic activity of nickel-molybdenum alloys deposits for both OER and HER, depending on electrodeposition c.d. value, were due to their chemical constitution (in terms of nickel and molybdenum concentrations), structures, and surface structure.
