Based on a MK 40 sulfocation exchange membrane, a hybride electrode material containing nanodispersed copper is prepared. The methods of scanning electron microscopy and X ray diffraction (XRD) analysis reveal the formation of copper agglomerates measuring 250-470 nm and consisting of indi vidual particles of 20-30 nm. The procedure of multistage chemical deposition of copper into the ion exchange carrier makes it possible to obtain a continuous cluster of metal particles which determines the elec tron conducting properties of the resulting hybrid material. The electrochemical activity of the nanocompos ite electrode is studied in the reaction of nitrate ion electroreduction. Nanodispersed copper deposited into the membrane is shown to intensify the electroreduction of nitrate ions by a factor of 1.5-2 as compared with a compact copper electrode. The electroreduction of nitrate ions on compact copper is shown to involve 6 electrons, whereas the electroreduction on the nanocomposite involves 8 electrons. The electroreduction products of nitrate ions are identified by the IR spectroscopy method.
