A novel MnO2/graphene (G)/nickel foam (NF) composite as supercapacitor electrode was fabricated by a facile electrochemical deposition approach for the first time. The approach includes electrophoretic deposition of G on NF (EPD-G/NF) and electrodeposition of MnO2on EPD-G/NF (MnO2/EPD-G/NF). Compared with other methods for preparing MnO2/G composite, our green strategy avoids using harsh chemicals (e.g. hydrazine) or high temperature treatment for reducing graphene oxide. Owing to unique structure, specific capacitance (Cs) of the MnO2/EPD-G/NF electrode is as high as 476Fg−1at high current density of 1Ag−1in 0.5M Na2SO4solution, which is the highest Csfor MnO2/G composites to date, and the Csis higher than that of MnO2/NF electrode. Furthermore, it also exhibits high rate capacity, such as 216Fg−1of Csat 10Ag−1. On the other hand, our strategy provides a versatile method for fabrication of other G-based composites with metal oxide/hydroxide or conducting polymer as supercapacitor electrode.
