In this report, a facile and efficient route for the production of ZnFe₂O₄ nanoparticles was explored by a solution combustion (SC) method with potential energy storage applications. The structural analysis through X-ray diffraction (XRD) confirmed the formation of a well-crystallized spinel phase while scanning electron microscopy (SEM) revealed a uniform nanoparticle distribution with a particle size of 40–60 nm. Moreover, electrochemical evaluations of the ZnFe₂O₄ nanoparticles, conducted using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) testing, and electrochemical impedance spectroscopy (EIS), demonstrated their exceptional performance as supercapacitor electrodes. These findings underscore the potential of ZnFe₂O₄ nanoparticle nanoparticles as advanced electrode materials, contributing to developing high-performance supercapacitors for next-generation energy storage solutions.
