Elevating performance of ZnSnO3/rGO nanomaterials for supercapacitors devices

The demand of energy increases globally, and it seeks the consideration of researchers to fabricate the energy storing devices to fulfill the uninterruptible demand of energy. Therefore, a similar approach was used here, and a ZnSnO₃/rGO composite electrode material was fabricated via facile solvothermal approach for supercapacitor application. The material was tested via different physical characterization techniques like X-ray diffraction (XRD), Energy Dispersive spectroscopy (EDS), scanning electron microscopy (SEM), Infrared spectroscopy (FT-IR) and Brunauer-Emmett-Teller surface area analysis (BET) was used to confirmed the crystallinity, composition, morphology, functionality and surface area of all fabricated material, respectively. Furthermore, the different electrochemical test (CV, GCD, ECSA, and EIS) were performed in alkaline 3 M (KOH) electrolytic solution to observe electrochemical behaviour of all prepared material. The ZnSnO₃/rGO composite shows a significant specific capacitance 1149.6 F g⁻¹ at C_d 1 A g⁻¹, having energy density (86.6 Wh kg⁻¹) and power density (368.3 W kg⁻¹). Thus, all these conclusions indicate that the ZnSnO₃/rGO is a best applicant for energy storage and conversion application.
