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.
