Electrocatalytic Materials of NiCoRe Electrodeposited Alloy for Alkaline Water Electrolysis

Abstract

The electrochemical behavior of electrodeposited Ni-Co-Re triple alloy is investigated in an alkaline medium and the kinetic parameters for the hydrogen evolution reaction are determined. The results are compared with those for electrodeposited Ni and Ni-Co alloy. The hydrogen evolution reaction occurs at a lower overpotential in the case of the triple alloy, which appears thereby as a promising electrocatalytic material for a negative electrode in an alkaline water electrolysis.
