Abstract: Flower-shaped CuO nanostructures have been prepared by complex precipitation method using NH3∙H2O as a complexing agent. The products were characterized in detail by combined means of X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and Brunauer–Emmett–Teller N2 adsorption-desorption analyses. Experimental results showed that the flower-shaped CuO nanostructures were composed of many coaxial CuO nanosheets in size of 3 μm in length and 61.61 nm in thickness. A detailed observation by TEM showed that the CuO nanosheets consisted of a large number of nanoparticles with the average size of about 40-70 nm and had porous structures with pore size of about 25.52 nm and surface area of 18.44 m2/g. The formation mechanism of the flower-shaped CuO nanostructures was discussed.
