Abstrakt: In this study, ceramic materials of Mg(Ti 0.99 Sn 0.01 )O 3 were synthesized and decorated on reduced graphene oxide, forming a nanocomposite of rGO/Mg(Ti 0.99 Sn 0.01 )O 3 (rGO/MTS001). The successful synthesis results were confirmed by XRD, UV-vis analysis, FT-IR, and SEM-EDS. The MTS001 has a flower-like morphology from scanning electron microscopy (SEM) analysis, and the nanocomposites of rGO/MTS001 showed MTS001 particles decorated on the rGO's surface. The electrochemical performance of rGO/MTS001 and MTS001 was investigated by determining the specific capacitance obtained in 1 M H 2 SO 4 solution by cyclic voltammetry, followed by galvanostatic charge-discharge analysis using a three-electrode setup. The rGO/MTS001 achieved a specific capacitance of 361.97 F g ‒1 , compared to MTS001 (194.90 F g ‒1 ). The capacitance retention of rGO/MTS001 nanocomposite also depicted excellent cyclic stability of 95.72% after 5000 cycles at a current density of 0.1 A g ‒1 . The result showed that the nanocomposite of ceramics with graphene materials has a potential for high-performance supercapacitor electrodes.
