Graphene-coated copper nanowire networks as a highly stable transparent electrode in harsh environments toward efficient electrocatalytic hydrogen evolution reactions

Copper nanowire networks (NWs) coated with a graphene layer through a carbon-enclosed chemical vapor deposition technique at a low temperature of 400 °C with a low sheet resistance of 23.2 Ω sq⁻¹ and a high transmittance of 83.4%, which is comparable to typical values of tin-doped indium oxide (ITO), as a transparent conducting electrode were demonstrated.
