Self-supported three-dimensional Cu/Cu2O–CuO/rGO nanowire array electrodes for an efficient hydrogen evolution reaction

We report the fabrication of self-supported Cu/Cu2O–CuO/rGO nanowire arrays on commercial porous copper foam, which exhibit excellent activity and durability for electrochemical hydrogen evolution, presenting a small onset potential of 84 mV and a low overpotential of 105 mV at a current density of...

Summary:We report the fabrication of self-supported Cu/Cu2O–CuO/rGO nanowire arrays on commercial porous copper foam, which exhibit excellent activity and durability for electrochemical hydrogen evolution, presenting a small onset potential of 84 mV and a low overpotential of 105 mV at a current density of 10 mA cm−2.
