It was pointed out that nanocomposite electrodes composed of MnO2 and functionalized rGO exhibited a high specific capacitance. Mao et al. [21] utilized the precipitation method to synthesize nanostructural MnO2 compounded with tetrabutylammonium hydroxide to stabilize graphene in various mass ratios. The...
