A New Spherical Catalyst For Hydrogen Evolution Reaction

Abstract

CuFeZn composite catalysts have been prepared on the graphite electrode by electrochemical deposition as electrocatalytic materials for hydrogen evolution reaction (HER). The etching process was applied on catalysts in caustic solution to leach out zinc and to produce a porous electrocatalytic surface for hydrogen evolution. The surface morphologies were investigated by scanning electron microscopy. HER activity is assessed by recording cathodic current–potential curves, cyclic voltammetry, electrochemical impedance spectroscopy and electrolysis techniques. The results show that etched catalysts have a compact and porous structure as well as a good electrocatalytic activity for the HER in alkaline media.
