Galvanostatically Deposited PtNi Thin‐Films as Electrocatalysts for the Hydrogen Evolution Reaction

Abstract: The synthesis of hybrid platinum materials is fundamental to enable alkaline water electrolysis for cost-effective H 2 generation. In this work, we have used a galvanostatic method to codeposit PtNi films onto polycrystalline gold. The surface concentrations of Ni (Γ Ni ) and Pt (Γ Pt ) were calculated from electrochemical measurements; the Γ Pt /Γ Ni ratio and electrocatalytic activity of these materials towards hydrogen evolution reaction (HER) in 1 M KOH show a strong dependence on the current density pulse… Show more
