|The possibility of obtaining nano dispersed copper(I) oxide by electrolysis on the alternating current of industrial frequency is shown. The parameters of electrolysis, influencing the electrochemical oxidation of copper in neutral solutions and the rate of formation of the copper(I) oxide powder, were studied. A comprehensive study of copper(I) oxide powders obtained by electrosynthesis using modern physicochemical methods (electron microscopy, X-ray phase analysis, IR spectroscopy and thermogravimetry) was carried out, which made it possible to establish their qualitative composition and particle sizes that make up these compounds. By varying the concentration of the electrolyte, the current density at relatively low electrolysis temperatures, nanodispersed powders with a high specific surface area and particle sizes of 5-30 nm were obtained. © 2021, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.
