摘　　要：以离子液体为介质，采用一步化学热分解反应制备出直径为10nm左右，长度达40-110nm的氧化锌纳米棒。利用IR，XRD，TEM以及SAED等测试手段对其进行了表征。实验结果表明：体系中离子液体的加入对产物形貌有着重要的影响。同时讨论了氧化锌纳米结构的生长机理。ZnO nanorods were successfully synthesized by thermal decomposition of Zn（OH）2 in the ionic liquid 1-butyl-3-ethylimidazolium tetrafluoroborate. Their structure and morphology were characterized by means of infrared spectroscopy （IR）, X-ray powder diffraction （XRD）, and transmission electron microscopy （TEM）. The TEM results indicate that the diameter of nano-structure prepared was 10 nm, and length was 200nm. The XRD pattern reveals that the prepared ZnO nanorods belong to the hexagonal crystal system. The results show that ionic liquid can not only act as a reaction medium but also modify ZnO nanorods in the reaction. In this paper the growth mechanics of zno nano-structure was preliminary studied.
