Physical and chemical activation conversion methods were used to activate OPF. The structural and physiochemical properties of the activated carbon derived from OPF were studied and analyzed using FESEM, XRD, BET, XPS, and FTIR. The electrochemical properties of supercapacitors fabricated from POPF and COPF were studied and reported using cyclic voltammetry, Galvanostatic charge discharge and electrochemical impedance spectroscopy. © 2020 Elsevier B.V. publisher: Elsevier B.V. date: 2021 type: Article type: PeerReviewed identifier: Tobi, A.R. and Dennis, J.O. and Zaid, H.M.
