Sea Urchin-like and Plates CuO Nanostructured Prepared by Simple Thermal Decomposition Process

Abstract

Sea urchin-like and plates CuO nanostructured have been prepared via a thermal decomposition reaction of CuC2O4 at 300°C for 1 h. The morphology and structure of the synthesized sea urchin-like structures were characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). The results show that these sea urchin-like and plates CuO nanostructured presents monoclinic structure and typical diameters of 300 to 500 nm with a self-assembly of nanoparticles and average diameter of about 23 nm. The as-prepared CuO nanostructured have a high surface area of about 39.83 m2/g. Finally, a possible growth mechanism was also proposed to explain the formation of sea urchin-like and plates CuO nanostructured.
