采用二水醋酸锌液相沉淀法合成了均匀、球形的ZnO纳米粒子。在水-乙醇混合溶液中制备了超细氧化锌。含锌阳离子的溶液可溶于水。表面活性剂三乙醇胺（TEA）可溶于乙醇。然后通过加入正丙胺使碱沉淀。发现球形氧化锌颗粒形态高度依赖于锌盐浓度、乙醇-水比率和表面活性剂添加剂。该方法可制得粒径为50-90 nm的白色ZnO粉体。氧化锌的形态通过透射电子显微镜（TEM）显示为粉末状，通过X射线衍射（XRD）显示氧化锌的结晶相结构，并且通过使用红外光谱（IR）的有机分析显示氧化锌残留。
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).
