【 摘 要 】

Nanostructured systems, including the products of copper ions recovery - nanoparticles of copper, copper(I) oxide or complex copper particles and copper oxides, have been obtained. Copper ions were reduced by tert-butylamine borane in aqueous solutions of poly(N-vinylpyrrolidone) at room temperature under air. Different synthesis conditions allowed controlling both the size of the resulting particles and the final product of the synthesis. The composition, morphology and size characteristics of nanocomposites were studied by methods of electron microscopy and XRD. The efficiency of the Cu/CeO2 catalytic system in the purification of hydrogen from CO was shown.
