Production of copper nanoparticles by electrochemical process

There are numerous methods for preparing copper nanoparticles of which electrodeposition is one of the most suitable and simplest. The electrolyte used in the present investigation is an acidified aqueous solution of copper sulphate with suitable additives. By varying the input dc voltage with a constant current, a spongy layer of copper particles is deposited on the cathode surface. Particles are collected and characterized by XRD and UV-Vis, the surface morphological characterization is done by SEM and TEM.
