Kinetics of Hydrogen Evolution Reaction on Nickel‐Zinc‐Phosphorous Electrodes

Abstract

Ni‐Zn‐P electrodes were prepared by subsequent deposition of Ni, Ni‐P, and Ni‐Zn‐P layers. The topmost Ni‐Zn‐P layer was obtained by gradual addition of zinc to the plating bath. The obtained electrodes are more stable and more active toward the hydrogen evolution reaction than Ni‐Zn alloys. They are characterized by low Tafel slopes and large surface roughness of 104 They may be attractive candidates for the alkaline water electrolysis.
