We reported a facile approach to synthesize nanocomposites with Mn 3 O 4 nanoparticles anchored to graphene nanosheets by one-step solvothermal process, which combined the growth of Mn 3 O 4 nanoparticles and the reduction of graphene oxide. It was found that Mn 3 O 4 nanoparticles with size of 3–5 nm homogeneously deposited on graphene nanosheets. The electrochemical properties of graphene/Mn 3 O 4 nanocomposite were studied as electrode materials for supercapacitors. The graphene/Mn 3 O 4 nanocomposite exhibited a specific capacitance of 147 F g − 1 in 1 M Na 2 SO 4 aqueous electrolyte and a good rate property. The improved electrochemical performance may be attributed to the increased electrode conductivity in the presence of graphene network. |
