Graphene nanosheets (GNS) have garnered significant attention due to their exceptional properties and wide-ranging applications. This research aims synthesize GNS from coconut shells candlenut compare performance in Fe ion adsorption electrochemical properties. Both were used as raw materials, the pyrolysis method was chosen produce large-scale GNS. The characterized using Raman spectroscopy, X-ray diffraction, FTIR, FESEM-EDX, AAS, measurements, including CV EIS on modified electrodes. New findings this study reveal that derived exhibit thinner layers fewer defects compared with those shells. structural advantage contributes superior efficiency better performance, making more suitable for applications flexible electronics devices. Furthermore, synthesis effectively reduces amount of oxides associated GNS, enhancing material's potential high-performance produced showed an effectiveness 0.33 ± 0.012 mg/g, a charge transfer resistance 0.78 kΩ, capacitance 108.8 F/g, indicating promising role future technological
