Nickel mesh electrodes were used as the working electrode. Iron and copper were electrochemically
deposited on the nickel mesh in different amounts. When electrochemical
coatings had been carried out, different currents were passed from the circuit at different
times and coatings were accumulated at constant load. The prepared electrodes called as
FexCux, FexCu3x and FexCu9x and these electrodes have been used for hydrogen evolution
reaction (HER). The surface morphologies were investigated by scanning electron microscopy.
The HER activity is assessed by recording cathodic currentepotential curves, cyclic
voltammetry, electrochemical impedance spectroscopy. The results show that FexCu9x
catalysts have a compact and porous structure as well as good electrocatalytic activity for
the HER in alkaline media.
