A simple approach was developed to synthesize the three-dimensional (3D) hybrid of manganese dioxide (MnO2) and graphene foam. The morphology of the MnO2 nanostructures can be readily controlled by the solution acidity. Furthermore, we demonstrate that, serving as a free-standing supercapacitor elec...
