Abstract

In this paper, highly dispersed copper oxide (CuO) nanoparticles with different size and morphology have been successfully prepared by a quick-precipitation method in DMAC-water mixed solvent. The as-prepared CuO nanoparticles were characterized by high resolution transmission electron microscopy (HRTEM) and x-ray diffraction (XRD). Several kinds of CuO particles with different morphology were obtained including panicle-shaped, spherical-shaped, spindly-shaped and rod-shaped CuO particles. The effects of processing parameters on the size and shape of CuO particles such as volume ratio of DMAC/water, adding temperature of NaOH and molar ratio of Cu²⁺/OH^- were investigated. The nucleation and growth kinetic of the resulting CuO particles were also discussed.
