Electrochemical behavior of manganese oxide/graphene composites using various reducing agents |
| 초록 |
Manganese Dioxide (MnO2)/Graphene composites were prepared by using variety of reducing agent Such as DMF(dimethyl formamide), Ethanol, Ethylene glycol was used to reducing potassium permanganate. According to reducing agent, MnO2/graphene composites exhibited different electrochemical characteristics. MnO2/graphene composite Prepared by ethanol showed higher specific capacitance than other composites. These properties are resulted from both their various structure and morphology of manganese oxide. The structure and morphology of the composites were examined by Field-emission Scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy(FT-IR). Electrochemical properties were characterized by cyclic voltammetry (CV) and Charge-Discharge Test in 1M Na2SO4 aqueous electrolyte of 3-electrode system. |
