RADICAL MECHANISM OF FORMATION OF Cu-Re AND Pb-Re COMPOSITES IN GASEOUS PHASE BY THERMAL DECOMPOSITION OF TRANS-TETRACHLORODI-μ-PROPIONATO DIRHENIUM(III)

Abstract

Reactions of individual trans-tetrachloro-di-μ-propionato dirhenium(III) thermal decomposition in dynamic inert atmosphere were investigated. Using a radical reaction of transportation in gaseous phase, Cu-Re and Pb-Re composites were obtained on a ceramic surface. Free radicals C2H5• were detected by reaction with metal Cu and Pb mirrors. Cu-Re and Pb-Re composites were studied by XRD, micro-X-ray spectral and SEM analysis. Cu-Re composites contain nanodendrites of Cu which «grow» from a Re base and most likely have a nanotube structure. Dimensions of the nanotubes can vary from 100 nm to 1 μm.
