| Abstract: | Precursor ZnC_2O_4 is synthesized by solid state reaction of ZnSO_4·7H_2O with Na_2C_2O_4 at room temperature. Nanocrystalline ZnO is obtained by decomposition of the precursor at 400℃for 3h. The component, size and shape of this product have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results show that ZnO nanocrystalline has hexagonal structure, the particles are spherical and have a mean diameter of about 28nm. |
