Box. 17011, Doornfontein, Johannesburg, 2028, South Africa, Department of Physics &amp; Electronics, CHRIST University, Bangalore, India, TrEST Research Park, Kerala, Trivandrum, India Description An account of the resource Biomass waste derived from jackfruit (Artocarpus heterophyllus) cores is used to fabricate hierarchical porous activated carbon through chemical activation with Iron(III) chloride (FeCl3) and potassium hydroxide (KOH). Jackfruit is an abundant agricultural by-product in tropical regions, including India, Bangladesh, and Sri Lanka. The activated carbon derived from jackfruit provides a sustainable, low-cost, and high-performance alternative to conventional carbon materials for supercapacitors, thereby aligning with waste valorisation strategies. The prepared carbon displays hierarchical porous structures of both micro and mesopore architectures. They are amorphous and contain functional oxygen groups, as confirmed by X-Ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy (FTIR). A high surface area (1251m2g?1) was obtained via Brunauer-Emmett-Teller (BET) analysis. The electrochemical performances, via cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charge/discharge (GCD) show high specific capacitance of 310Fg?1 at 0.8Ag?1 from GCD, 331Fg?1 at 10mVs?1 from CV, and a charge transfer resistance of 0.1410?cm2, in three electrode configuration and showing good cycling stability of 87% over 2500 cycles. These results suggest that the activated carbon offers potential application in low-cost and renewable production of carbon materials for supercapacitors applications. 2026 Elsevier Ltd.
