Aleksandrov, G. Ostaeva, A. Papisova, I. Papisov, L. Petrova, V. Prikhod'ko, D. Fatyukhin] Contact between a steel surface and a mixed solution of poly(N-vinylpyrrolidone) and copper sulfate leads to the reduction of copper(2+) ions and the formation of a nanocomposite consisting of copper nanoparticles and the polymer. Ultrasonic treatment of the reaction mixture yields a sol of the nanocomposite, the particles of which contain metal nanoparticles and their aggregates with sizes of 10-100 nm shielded by the polymer. The nanocomposite has been used as a precursor of a catalyst for steel nitriding, i.e., copper oxide, which is formed at high temperature via degradation of the nanocomposite and oxidation of copper nanoparticles. Owing to the small particle sizes, this catalyst is substantially more active than an analogous catalyst obtained by reducing copper ions in the absence of the polymer.
