Abstract

Vetiver root waste from the distillation process of essential oils production is rich in cellulose, hemicellulose, and lignin. These biomass components have great potential to be utilized as a precursor for porous activated carbon. The activated carbon was synthesized using pyrolysis at high temperatures, followed by KOH activation, followed by hydrothermal method. The characteristic of activated carbon was analyzed using X-ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), and Raman Spectroscopy. These results show that MnO2 altered the carbon structure during the impregnation of MnO2 into an activated carbon structure. Electrochemical measurement was conducted using Ag/AgCl and Pt wire using a three-electrode system. The specific capacitance of porous activated carbon is 218 F/g at a current density of 1 A/g. After MnO2 impregnation, the specific capacitance was improved to 443 F/g at the same current density. It proves the potential of activated carbon impregnated with MnO2 as electrodes for supercapacitors.
