Abstract
- Thanks to the unique architectural construction, nano-sized activated carbon materials demonstrate superior performance as supercapacitor electrode materials compared to conventional carbon-based materials. In this work, we demonstrated biowaste-derived tubular-like porous architecture synthesis through the KOH activation with different mass ratios (precursor/KOH) viz. 1:0.20, 1:0.25, and 1:0.30 by using a one-step pyrolysis strategy. The young coconut husk (YCH) waste was used as a carbon resource. All the synthesized samples were characterized using several techniques, including a scanning electron microscope combined with energy-dispersive X-ray, X-ray diffraction, and X-ray diffraction, to evaluate the surface topography, elemental composition, and crystalline nature of the samples. A cyclic voltammetry and galvanostatic charge/discharge technique was employed to assess their capacitive behavior. The surface morphology of YCH-0.25 shows a tubular-like porous architecture with a diameter in the range of 26-144 nm. According to CV and GCD, curves The YCH-0.25 sample attains the optimum capacitive performance as high as 231 F g−1 and 297 F g−1, respectively. This work provides a new perspective on the future management of young coconut husk waste in terms of promising clean energy technologies. [ABSTRACT FROM AUTHOR]
