COPPER NANOPARTICLES IN THE ELECTROCATALYTIC HYDROGENATION OF ACETOPHENONE

Abstract

Copper nanoparticles were obtained by chemical reduction sodium borohydride and hydrazine hydrate аt present and without the addition of water-soluble polymers (PVA, PVP and TWEEN 80) as stabilizers. Their structure and morphological features have been studied by X-ray phase analysis and electron microscopy. Obtained copper nanoparticles have been used to activate a cathode in the electrohydrogenation of acetophenone in an aqueous- alcohol-alkaline catholyte medium. A higher electrocatalytic activity of copper nanoparticles prepared using sodium borohydride was established, which is insignificantly higher than that of copper nanoparticles produced by the method of electric explosion of a wire and noticeably higher than that of electrochemical copper powder.
