Electrochemical energy storage and photoelectrochemical performance of Ni1-XZnXFe2O4 nanoparticles

In this study, the mixed Ni-Zn nanoparticle's noteworthy shape is attained using a solvothermal reflux technique. The distinctive crystalline spinel cubic structure, morphology with the correct stoichiometric element ratio, and surface analysis was confirmed by X-ray diffraction (XRD), Field emission scanning electron microscopy (FE -SEM), energy-dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) analysis. A three-electrode device was used to confirm the electrochemical properties of the ma-terials as they were produced. Electrochemical performances attest to the electrode material's electrochemical behavior. Cyclic voltammetry (CV) and Galvanostatic charge-discharge (GCD) techniques are used to investigate the electrochemical performance in a 1 M KOH electrolyte. The Ni0.7Zn0.3Fe2O4 (ZNF3) electrode performs better than the other electrodes such as Ni0.9Zn0.1Fe2O4 and Ni0.8Zn0.2Fe2O4 (ZNF1 and ZNF2) electrodes in terms of specific capacitance (Cs), measuring 152 F/g, at a current density (CD) of 2 A/g. The study of the linear sweep voltammetry (LSV) curve revealed that the ZNF3 electrode had a higher photocurrent density.
