Fabrication of KOH-modified reduced graphene oxide electrodes and their electrochemical performance |
| 초록 |
Chemical modification of graphene nanosheets by KOH was examined as a way to enhance the specific capacity of graphene nanosheets in supercapacitor. KOH activation method efficiently allows various pore size distributions. Herein, we report the modification of the graphene nanosheets using 10M KOH solution and their resulted electrochemical performance as supercapacitor electrode materials. These results demonstrated the importance and great potential of graphene oxide in the development of high-performance supercapacitor based on KOH activation. The morphology, structure of the composites were analyzed by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). Electrochemical properties were characterized by Cyclic Voltammetry (CV) and Charge-Discharge(CD) in 6M KOH electrolyte. |
