Much effort has been made to synthesize and tailor the microstructures of porous carbon materials via various activation procedures. In particular, the chemical activation of various carbon sources using KOH as the activating reagent is very promising because of its lower activation temperature and higher yields, and well-defined micropore size distribution. 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. |
