Abstract

The increase in energy crisis and environmental concerns are now considering as major hurdle in way to sustainability and clean energy solution. Metal sulfides have been investigated for the fabrication of energy conversion ad storage devices to overcome the effect of energy demand. In this concern, a microemulsion mediated hydrothermal method was employed for the successful synthesis of pure Co₄S₃ and Ce₂S₃-Co₄S₃ binary nanocomposite materials. This study was investigated for Supercapacitor application using cyclic voltammetry and electrochemical impedance spectroscopy. The scanning electron microscope analysis of composite material showed compact smooth morphology with strong interparticle interactions. The cyclic voltammetry was assessed for the determination of specific capacitance and energy density of material. The Ce₂S₃-Co₄S₃ binary nanocomposite demonstrated excellent specific capacitance and energy density value of 952 F/g and 33.06 Wh/kg, respectively. The higher capacitance and energy density value of Ce₂S₃-Co₄S₃ binary nanocomposite is due to its strong synergistic interaction between both metals. Similarly, the electrochemical impedance spectroscopy demonstrated the effective kinetic behavior of Ce₂S₃-Co₄S₃ binary nanocomposite. This recommends composite material a strong candidate in class of metal sulfide for greener sustainable solutions.
