- 中文摘要: The liquid precipitation method using zinc acetate dihydrate was applied for the synthesis of uniform and spherical ZnO nanoparticles. The ultrafine zinc oxid was prepared in a water-ethanol mixture solution. The solution containing zinc cation was soluble in water. The surface-active agent triethanolamine (TEA) was soluble in ethanol. Then alkali precipitated by adding n-propylamine. The spherical zinc oxide particle morphology was found to be highly dependent on the zinc salt concentration, ethanol-water ratio, and the surface-active agent additive. The process can produce white ZnO powder of 50-90 nm in size. The morphology of zinc oxide showed a powder shape by transmission electron microscopy (TEM), the crystallization phase structure of zinc oxide by X-ray diffraction (XRD), and the zinc oxide remaining by using an organic analysis by infrared spectroscopy (IR).
