SYNTHESIS AND CHARACTERIZATION OF Cu NANOPARTICLES PREPARED BY THERMAL DECOMPOSITION OF Cu-OLEATE COMPLEX

Abstract

Cu nanoparticles have been synthesized by thermal decomposition of Cu -oleate complex, which was prepared by the reaction with CuCl 2 and sodium oleate in water solution. The monodispersed Cu nanoparticles were produced by controlling temperature (290°C). TEM images of the nanoparticles showed two-dimensional assembly of particles with diameter of 16.2 ± 2.9 nm , demonstrating the uniformity of these nanoparticles. EDX spectrum and XRD peaks of the nanoparticles showed the highly crystalline nature of the Cu structures. The decomposition of Cu -oleate complex was analyzed with TGA and the crystallization of Cu nanoparticles was observed with XRD.
