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
