dc.description.abstractHere, the electrochemical performance of ZnO@sulphur-doped carbon particles from banana peels in three stages for use in supercapacitors was investigated. The first stage involves the production of activated carbon from banana peel by NaOH activation (BPAC). The second stage involves the production of sulphur-doped BPAC (BPAC-S) by sulphuric acid activation of the obtained BPAC sample. In the third stage, the ZnO-doped BPAC-S sample was produced by ZnO doping using hydrothermal process. The electrochemical performances of the obtained BPAC-S and ZnO-doped BPAC-S samples were investigated in supercapacitor application as an electrode material. The characterization of the obtained materials was performed by SEM, FTIR, XRD, EDS and nitrogen adsorption/desorption analyses. In particular, there are significant changes in the capacitive response with the changes in the porous structure of the composite material with the addition of ZnO. In supercapacitor applications, the electrochemical properties of these electrode materials were investigated by CV, high charge/ discharge and EIS analyses. The maximum specific capacitances for the BPAC-S and ZnO-doped BPAC-S at 10 mA/g were 147.03 and 224.15 F/g.
