Copper Nanoparticles, Electrodeposition, Electrolyte, MorphologyAbstract
In the present study Copper Nanoparticles (Cu NPs) were prepared on the aluminium substrate by the electrodeposition technique from an aqueous electrolyte prepared from aqueous solution of copper sulphate and citric acid at room temperature. The morphology, chemical composition and crystal structure of the prepared (Cu NPs) were characterized using scanning electron microscope (SEM), energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD) techniques. The SEM images confirmed the deposition of uniform and highly dense spherical copper nanoparticles on the aluminium substrate. The EDX spectra confirmed the presence of copper on the substrate with no impurities. The crystallite size of the electrodeposited (Cu NPs) was calculated using Debye–Scherrer’s formula and found to be around 65 nm. By varying the deposition time and the concentration of electrolyte the growth of Cu NPs on the substrate can be controlled.
