摘要

NiS/S nanoparticles were synthesised through a solvothermal process utilising acetone, ethanol, and methanol as solvents. Techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Brunauer–Emmett–Teller (BET) analysis revealed that the choice of solvent significantly affected the structural, morphological, and surface properties of the synthesized nanoparticles. Cyclic voltammetry (CV), galvanostatic charging-discharging (GCD), and electrochemical impedance spectroscopy (EIS) studies highlighted the superior performance of NiS/S nanoparticles synthesised using acetone. This material exhibited enhanced specific capacitance and reduced charge-transfer resistance, attributed to its higher surface area, improved crystallinity, and uniform morphology. Electrochemical results highlight the crucial influence of solvent selection on the properties of NiS/S nanoparticles, identifying acetone as the optimal solvent for producing efficient electrode materials for energy storage applications.
