Production of Nanocopper by Electrodeposition Methods

Nano copper powder was prepared by electrochemical techniques (electro-deposition), a cell consisting of two electrodes made of copper plate (anode) and a steel plate (cathode). Current densities 1, 5, 10 A/dcm2 were used; all electro deposition experiments were carried out at ambient temperature. The dissolution of copper at the anode and the reduction of copper ions at the cathode were collected as a powder at the steel plate. Scanning electron microscopy and x-ray diffraction analysis were performed. Results showed that a particle size was a function of current density applied, as current density decreased, smaller particle size obtained. Removal of electro deposited copper over substrate was easier at lower current densities used, due to less adhesion of copper to substrate.
