Structural, Thermal, And Electrochemical Insights Into Znfe₂O₄ Nanoparticles Synthesized Via Co-Precipitation

Abstract

In this work, ZnFe₂O₄ nanoparticles were successfully synthesised by a simple, high yield and low-cost co-precipitation method. The ZnFe₂O₄nanoparticles were fully characterized by X-ray diffraction analysis (XRD), scanning electron microscope (SEM) with (EDX), Fourier transform infrared spectroscopy (FTIR) and thermal analysis (TG/DTA). XRD and FTIR analyses reveal that the synthesized ZnFe₂O₄ nanoparticles were of phase pure with cubic structure. Morphological study of FESEM images reveals that the particles were in quasi-cubic shape composed of tiny blocks and flakes. EDX spectrum confirmed the elemental composition of Fe, Zn and O in the synthesized ZnFe₂O₄ nanoparticles. Thermo-gravimetric and differential thermal analysis (TG/DTA) method was used to confirm the formation of ZnFe₂O₄ nanoparticles. From the CV analysis, higher capacitance value observed for the lower scanning rate 2mV/s. The electrochemical performance suggesting that the synthesized of ZnFe₂O₄ nanoparticles could be suitable for super capacitance application.
