The Synthesis of Bridging Carbon Particles with Carbon Nanotubes from Areca catechu Husk Waste as Supercapacitor Electrodes

摘要

This study examines the synthesis of carbon particles with nanotubes as electrodes for supercapacitors.The electrodes were made from areca catechu husk without the addition of adhesive materials. Therewas a multi-activation process including chemical and physical activation using KOH activator andCO 2 . Physical activation time is the main factor for consideration in this discussion. The addition ofactivation time has an effect on the physical and electrochemical properties of supercapacitorelectrodes. Carbon hollow fiber is clearly visible on the surface of the electrode with varying sizes ofouter and inner diameters in the nanometer range. The results show there was an incredibleperformance by ACF-2.5 sample activated for 2.5 hours. ACF-2.5 sample delivered optimumcapacitive properties of 165 F g -1 with a maximum surface area of 757.449 m 2 g -1 . Thermogravimetricanalysis and the degree of crystallinity were also carried out to strengthen the electrode analysis ofsupercapacitors.
