Abstract

A simple approach was developed to synthesize the three-dimensional (3D) hybrid of manganese dioxide (MnO ₂) and graphene foam. The morphology of the MnO ₂ nanostructures can be readily controlled by the solution acidity. Furthermore, we demonstrate that, serving as a free-standing supercapacitor electrode, this novel three-dimensional hybrid gives a remarkable specific capacitance (560 F/g at the current density of 0.2 A/g) and excellent cycling stability.
