SYNTHESIS AND EVALUATION OF COPPER/COPPER OXIDE (II) NANOPARTICLES ON GOLD SURFACE BY CHEMICAL OXIDATION METHOD

A new method has been presented for the synthesis of copper (Cu)/copper oxide (CuO)-nanoparticles (NPs), based on the process of corrosion and oxidation of Cu-NPs on the surface of the gold electrode by nitric acid. Cu-NPs were deposited on the surface using potentiometric method. The high concentra...
