Kinetics of Hydrogen Evolution Reaction on Nickel-Zinc-Phosphorus Electrodes
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 10(4). They may be attractive candidates for the alkaline water electrolysis.
