摘要

The design and fabrication of high-performance supercapacitors requires innovative materials with unique energy storage capabilities. Herein, a novel Nucleosome like MnFe2O4@TiO2@MWCNTs composite is fabricated and considered for its potential in energy storage applications. The synthesis and structural parameters of composite materials are inspected through XRD (X-ray diffraction), SEM (Scanning electron microscopy) and TEM (Transmission elctron microscopy). High resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS) and energy dispersive x-ray spectroscopy (EDX) analyses are also used as further confirmation tools. Cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) techniques are used to estimate the electrochemical properties. The composite delivered a maximum specific capacitance of 786.26 F g− 1 at 2.5 mA in a two-electrode configuration. The assembled MnFe₂O₄@TiO₂@MWCNTs device showed maximum energy density of 33.03 Wh kg⁻¹ at a power density of 458.47 W kg⁻¹. These results demonstrate the composite potential for advance energy storage devices.
