ABSTRACT

A carbon nanofber was produced from the Areca catechu husk as a supercapacitor electrode, utilizing a chemical activation of potassium hydroxide (KOH) at diferent concentrations. One-stage integrated pyrolysis both carbonization and physical activation were employed for directly converting biomass to activated carbon nanofber. The morphology structure, specifc surface area, pore structure characteristic, crystallinity, and surface compound were characterized to evaluate the infuence on electrochemical performance. The electrochemical performance of the supercapacitor was measured using cyclic voltammetry (CV) through a symmetrical system in 1 M H2SO4. The results show that the KOH-assisted or absence activation converts activated carbon from aggregate into a unique structure of nanofber. The optimized carbon nanofber showed the large specifc surface area of 838.64 m2 g−1 with the total pore volume of 0.448 cm3 g−1, for enhancing electrochemical performance. Benefcial form its unique structural advantages, the optimized carbon nanofber exhibits high electrochemical performance, including a specifc capacitance of 181.96 F g−1 and maximum energy density of 25.27 Wh kg−1 for the power density of 91.07 W kg−1. This study examines a facile conventional route for producing carbon nanofber from biomass Areca catechu husk in economical and efcient for electrode supercapacitor.
