A uniform three-dimensional (3-D) graphene nanodots-encaged porous gold electrode has been fabricated via ion beam sputtering deposition (IBSD).As shown in Fig.1 and Fig.2,the electrodes were fabricated using Au target and a composite target of Al and graphite,which were simultaneously sputtered onto glass substrates by Ar ion beam,followed with hydrochloric acid corrosion to afford the porous structure.
