Enhancing porous electrodes through carbon activation of palm shell with gel activating agent
Activated carbon derived from biomass offers several advantages, including high surface area, customizable pore sizes, abundance, resilience across temperatures, and cost-effectiveness. This study focuses on exploring the potential of palm shell as a renewable alternative for supercapacitor electrode materials. Specifically, it investigates the utilization of a gel composed of NaOH and PVA for activating carbon. Here, palm shell undergoes chemical activation, and its resulting activated carbon’s structural and physicochemical properties are comprehensively examined using XRD, FTIR, and BET measurements. The investigation delves into the electrochemical properties using cyclic voltammetry, galvanostatic charge–discharge, and electrochemical impedance spectroscopy of electrodes fabricated from chemically activated carbon derived from palm shells. The activated carbon enhanced a surface area of 216.062 m2 g−1 and a pore volume of 0.1468 cm3 g−1, and it is produced through the innovative approach of gel-based activation. This research highlights the potential of palm shell-derived activated carbon as a viable, sustainable, and efficient material for supercapacitor electrodes.
期刊介绍:
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
