In this work, an intriguing replicating and an embossing strategy was developed to fabricate self-supported three-dimensional (3D) porous reduced graphene oxide (rGO) film towards high-performance electrochemical capacitors. The unique 3D porous rGO film delivered a large specific capacitance (SC) of 206 F g(-1) at 1 A g(-1), and even 141 F g(-1) at a current density of 10 A g(-1), and desirable electrochemical stability in 1 M H2SO4 electrolyte, owing to its appealing micro-structural feature.
