One-step co-clectrodeposition was applied to prepare graphene-zinc oxide nanowalls (GZNWs) composite, where graphene oxide was electrochemically reduced and zinc oxide was electrodeposited simultaneously. The morphologies and the electrochemical properties of GZNWs were obviously influenced by the electrodeposition time The contrast experiments illuminate that GZNWs presented superior electrochemical activity.
