Investigating the electrochemical behavior of the CNT/Fe2O3 nanocomposite revealed compelling insights. TEM analysis confirmed the uniform attachment of Fe2O3 nanoparticles to the surface of CNTs. Consequently, in the three-electrode system, the CNT/Fe2O3 nanocomposite hybrid electrode exhibited impressive electrochemical performance. Achieving a high capacitance of approximately 512 F/g at a current density of 1 A/g, the CNT/Fe2O3 nanocomposite electrode showcased a remarkable energy density of 29.5 Wh/kg at a power density of 2.8 kW/kg. The exceptional electrochemical properties of CNT Fe2O3 nanocomposites position them as promising electrode materials for supercapacitors.
