摘要

The present investigation demonstrates the creation of NaFeO2/rGO through an easy hydrothermal approach. Physical investigations showed that NaFeO2/rGO had a unique nanostructure with enhanced surface area, conductivity, crystallinity and shape, resulting in impressive electrode material. Scanning electron microscopy studies revealed that NaFeO2 was closely dispersed on rGO and Brunner-Emmett-Teller analysis indicated that the electrode substance had a significant surface area. The electrochemical investigation of manufactured materials was evaluated using 3 electrodes in basic electrolyte solution of 3.0 M KOH. The synthesized NaFeO2/rGO demonstrated a remarkable greater specific capacitance (Cs) (1221.97 F/g) in contrast to pure NaFeO2 at 1 A/g. Additionally, nanocomposite represented an elevated energy density (Ed) (33.75 Wh/kg) and power density (Pd) (223 W/kg) together with extraordinary cyclic stable activity (5000th cycle). The increased electrochemical efficiency of composite is due to the combined effect of NaFeO2 and rGO which offer a significant area for contact and efficient charge transfer routes. These properties of the NaFeO2/rGO nanocomposite offer excellent stability and cost effectiveness, as well as a promising alternative for usage in supercapacitor applications in future.
