Аннотация
In this study, we improved the capacitance of carbon based reduced graphene oxide (rGO) and metal oxide based MnO2 by preparing nanocomposites of rGO/MnO2 nanocomposite using chemical synthesis method. The prepared nanoparticles and nanocomposites are characterized by FTIR spectroscopy, XRD, PL spectroscopy and FESEM with EDAX spectroscopy. FTIR studies disclose the characteristic chemical bonding between the respective materials. The FESEM images demonstrate that the surface structure of rGO and MnO2 can be easily tuned by forming the composite of rGO/MnO2 materials leading to excellent process ability of the system. The super capacitive behaviors of nanocomposites are evaluated using cyclic voltammetry and galvanostatic charge-discharge techniques. The specific capacitance of rGO/MnO2 composite is high compared to that of MnO2 nanoparticle. In addition, impedance measurements of the MnO2 nanoparticles and rGO/MnO2 electrodes are executed proposing that the rGO/MnO2 composite electrodes are promising materials for super capacitor (186.6 Fg-1).
