Catalytic Surface Specificity of Ni(OH) 2 ‐Decorated Pt Nanocubes for the Hydrogen Evolution Reaction in an Alkaline Electrolyte

Because the hydrogen evolution reaction (HER) in alkaline electrolyzers is initiated by water dissociation, the hydrogen evolution kinetics are sluggish even on highly active Pt catalysts. Here, we have synthesized Ni(OH) 2 -decorated Pt nanocubes as a bifunctional catalyst to enhance the HER kin…
