Fund Project:

The Co-WC composite-coating electrode was prepared by electrolytic composite deposition. Its electrocatalytic activity in hydrogen evolution has been examined in a 7 mol/L KOH solution by steady-state polarization and AC impedance technology. The results show that the composite-coating is catalytically more active than Co electrode due to the increase in its real surface areas and the decrease in the standard free energy of activation. The electrode shows an excellent stability in long-term electrolysis and good resistance against power interruption.
