Synthesis of Cu Nanoparticles Prepared by Using Thermal Decomposition of Cu-oleate Complex

ABSTRACT

In order to obtain well-dispersed Cu nanoparticles, we synthesized Cu nanoparticles by using thermal decomposition of Cu-oleate complex, which was prepared by the reaction with CuCl₂ and sodium oleate in aqueous condition. The resulting well-dispersed Cu nanoparticles were synthesized by autoclave. TEM image showed well-dispersed Cu nanoparticles with diameter of 8.9±1.3 nm. 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. UV-Vis absorption spectrum of Cu nanoparticles is also observed.
