摘要

This research paper tackles two pressing global issues first is the rising energy demands and second is effective waste management. It presents innovative strategies that repurpose bio-waste for energy storage, focusing on activating Murraya koenigii seeds using ZnCl₂ to produce activated carbon (MKAC). The study carefully examines the structural, textural, and electrochemical properties of MKAC through advanced techniques such as BET analysis, XRD, and Raman spectroscopy, SEM, and XPS, CV, IMP and GCD. The findings reveal an impressive surface area of approximately 798 m2 g−1, corresponding to a specific capacitance of about 178.98 F g−1 at a current density of 0.5 mA cm−2 for Cell-2 (MKAC). Additionally, the material exhibits a specific energy of roughly 16.32 Wh kg−1 and a power density of around 436 W kg−1, showcasing MKAC’s potential for energy storage applications. This research not only advances sustainable energy technologies but also underscores the critical role of bio-waste in addressing environmental challenges.
