Synthesis and characterization of cu nanoparticles prepared by thermal decomposition of Cu-oleate complex

Cu nanoparticles have been synthesized by thermal decomposition of Cu-oleate complex, which was prepared by the reaction with CuCl2 and sodium oleate in water solution. The monodispersed Cu nanoparticles were produced by controlling temperature (290 degrees C). TEM images of the nanoparticles showed two-dimensional assembly of particles with diameter of 16.2 +/- 2.9 run, 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.
