Synthesis, Characterization And Electrochemical Studies Of Mgfe2o4 Qds For Efficient Electrochemical Supercapacitor Electrode

Abstract

In this study, MgFe₂O₄ quantum dots (QDs) were synthesized using a cost-effective co-precipitation method. The synthesized MgFe₂O₄ QDs were thoroughly characterized through various methods, especially X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM) with Energy-Dispersive X-ray Analysis (EDX), X-ray photoelectron spectroscopy (XPS), Fourier Transform Infrared spectroscopy (FTIR), and Thermogravimetric and Differential Thermal Analysis (TG/DTA). XRD and FTIR analyses proved the spinel structure of the synthesized material, while XPS scrutiny verified the being of Fe 2p, Mg 2p, and O 1s in the MgFe₂O₄ QDs. Additionally, the electrochemical characteristics of the material were estimated using cyclic voltammetry (CV), revealing high electrochemical capacitance, outstanding rate performance, and stable cycling behaviour. These discovers indicate that MgFe₂O₄ QDs serve as promising electrode materials, exhibiting high particular capacitance and good retention. Owing to their remarkable synergistic effects, MgFe₂O₄ QDs hold significant potential for applications in various electrochemical fields.
