Abstract: In this study, NiV2O6 nanoparticles were successfully synthesized via the sol–gel method and evaluated for their dual applications in energy storage and antimicrobial activity. X-ray diffraction (XRD) analysis confirmed the formation of a crystalline NiV2O6 phase indexed to the anorthic system. Field Emission Scanning Electron Microscopy (FESEM) revealed a sheet-like morphology with particle sizes ranging from 1 µm to 100 nm, providing a moderate surface area and effective ion diffusion channels. X-ray photoelectron spectroscopy (XPS) analysis of Ni2+ and V5+ oxidation states in NiV2O6 nanoparticles, supporting the successful formation of the mixed-metal oxide structure. Electrochemical analysis demonstrated excellent capacitive behaviour, with a high specific capacitance of 640.91 F/g from cyclic voltammetry (CV) and 772.73 F/g from galvanostatic charge–discharge (GCD) measurements. The electrode exhibited remarkable energy storage performance, delivering an energy density of 20.79 Wh/kg and a high-power density of 1096.4 W/kg. Moreover, outstanding cyclic stability was observed with 92% capacitance retention after 1500 cycles. Furthermore, the NiV2O6 nanoparticles displayed significant antimicrobial activity against both bacterial and fungal organisms, attributed to the synergistic effect of Ni2+/V5+ ions and high surface reactivity. These findings highlight the potential of NiV2O6 nanoparticles as a multifunctional material suitable for next-generation energy storage devices and antimicrobial activities.
