摘要：

通过低温(60°C)水浴合成路线, 在油酸-无水乙醇混合溶液存在的条件下, 制备出Zn-ZnO核-壳间隙结构, 以原料Zn球为核, 并对产物直径大小产生直接影响, 而沿[001]晶面生长的ZnO纳米棒为壳, 棒直径为80~150nm, 而且核-壳之间存在一定的间隙空间. 适当的改变合成条件, 可以得到不同形态的Zn-ZnO核-壳结构. 通过XRD、SEM、TEM和FT-IR等分析手段, 对产物结构和性能进行了不同的分析, 并对Zn-ZnO核-壳结构的形成机理进行了讨论. 结果表明, 加入油酸-无水乙醇混合液对形成核-壳结构的间隙空间起到了重要的作用, 而外壳的ZnO棒尺寸大小可通过磁力搅拌来控制.

Abstract:

Core-shell gap structure of Zn-ZnO nanomaterials consisted of Zn sphere core and ZnO nanorods shell was synthesized by low-temperature water-bath process using oleic acid-ethanol (OA-ALKY) as assistant. The sizes of the products depended on the diameter of Zn spheres and the ZnO nanorods which formed on the shell grew along the [001] direction with a diameter of 80-150nm. Changing the reaction conditions could get different core-shell structures. Besides, these structures were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and Fourier transform infrared spectroscope (FT-IR), consequently the growth mechanism of the structures were proposed. The result indicates that adding oleic acid and ethanol mixture plays an important role in forming gap space of the core-shell structure, and the size of ZnO nanorods of the shell can be controlled by magnetic stirring.

Key words: zinc oxide, core-shell structure, gap space
