Biomass Derived Reduced Graphene oxide from Abelmoschus esculentus and Cucumis melo peels as electrode material for High Performance Supercapacitors

Abstract: Supercapacitors, an electrochemical energy storage device has been used as one of the powerful and advanced energy storage system. For these supercapacitors, Electrode material from plant source have largely been tried as carbon source due to their eco- friendly, economic nature, large surface area and outstanding electrochemical performance. In the Present research work, Reduced Graphene oxide have been synthesized by using Abelmoschus esculentus and Cucumis melo waste peels through Hydrothermal Carbonization method and reduced in eco- friendly manner by using Modified Hummer's method. The physical and chemical properties of the produced Reduced Graphene oxide were characterized using FT-IR spectroscopy, X- Ray Diffraction, FE-SEM, Energy Dispersive Analysis of X-Ray, Thermogravimetric Analysis. Capacitance behavior of the produced Reduced Graphene oxide of Abelmoschus esculentus and Cucumis melo waste peels are examined using Electrochemical analysis. Specific capacitance of Reduced Graphene oxide of Abelmoschus esculentus and Cucumis melo were found to be 149 F/g and 151 F/g respectively at a current density of 2 A/g.
