Electrosynthesized CuOx/graphene by a four

Here a facile four-electrode electrolysis system is firstly applied to synthesize a CuO x /graphene hybrid. The exfoliation of graphite via high electrolytic voltage and dissolution of copper via low electrolytic voltage are achieved simultaneously. CuO x /G with the highest content of CuO x shows superior electrocatalytic activity for oxygen reduction to hydrogen peroxide.
