KOH modified graphene nanosheets for supercapacitor electrodes

---

Abstract.
Chemical modification of graphene nanosheets by KOH was examined as a way to enhance the specific
capacity of graphene nanosheets in supercapacitor. Fourier transform infrared spectroscopy, Raman
spectroscopy and X-ray photoelectron spectroscopy were used to investigate the effects of the treatment
on the surface of the graphene nanosheets. The specific capacitance of 136 F g−1 was obtained for KOH
treated graphene by integration of the cyclic voltammogram, an increase of about 35% compared with
that for the pristine graphene nanosheets.

Keywords: Graphene, Modification, Supercapacitor
