A three-dimensional bi-continuous nanoporous gold (NPG)/nickel foam is developed though the electrodeposition of a gold–tin alloy on Ni foam and subsequent chemical dealloying of tin. The newly-designed 3D metal structure is used to anchor MnO 2  nanosheets for high-performance supercapacitors. The formed ternary composite electrodes exhibit significantly-enhanced capacitance performance, rate capability, and excellent cycling stability. A specific capacitance of 442 Fg −1  is achieved at a scan rate of 5 mV s −1  and a relatively high mass loading of 865 μg cm −2 . After 2500 cycles, only a 1% decay is found at a scan rate of 50 mV s −1 . A high power density of 3513 W kg −1  and an energy density of 25.73 Wh kg −1  are realized for potential energy storage devices. The results demonstrate that the NPG/nickel foam hybrid structure significantly improves the dispersibility of MnO 2  and makes it promising for practical energy storage applications.
