Abstract:
This work attempts to prepare the activated carbon from durian peels by employing chemical activation using sodium sulfite (Na2SO3) as the activating agent. Since durian peel contains sulfur in a form of sulfide, the as-prepared activated carbon would have the sulfur without any chemical doping process. The process parameters in this study were activation temperature (500-900 degrees) and impregnation ratio (durian to activating agent of 1:1, by weight). The specific surface area and pore structures were determined by nitrogen adsorption measurement and the elemental compositions were characterized by CHNSO analysis. The chemical structure and surface functionality were examined by X-ray photoelectron spectroscopy. Electrochemical storage capability of the obtained activated carbon was characterized in 6 M KOH using three-electrode configuration. We have found that specific surface area of the activated carbon is increased with activation temperature. However, the surface area slightly dropped at the temperature above 800 degrees. In addition, the sample with the highest surface area (1,440 m2 g-1), which was activated at 800 degrees, has lower specific capacitance (178 F g-1) than that activated at 700 degrees (183 F g-1). This can be due to the pseudocapacitance induced by organic sulfur functional group, thiophene, which can exhibit redox reaction involving one electron.
