以醋酸锌、草酸为主要原料，采用溶胶-凝胶法制备纳米 ZnO。在反应体系中加入表面活性剂十六烷基三甲基溴化铵（CTAB），成功制得短柱状及棒状结构的纳米 ZnO。借助 XRD 和 TEM 对产物的结构和形貌进行了表征。结果表明，产物属于纤锌矿结构的六方相 ZnO，并且，在棒状结构纳米 ZnO 的形成过程中 CTAB 起关键作用，改变反应体系中 CTAB 的加入量，可以实现纳米 ZnO 的形貌控制合成。讨论了棒状纳米 ZnO 可能的形成机理。

Nano-ZnO were synthesized from Zn( CH3 COO)2 ·2H2 O and H2 C2 O4 ·2H2 O by sol-gel method. The rod-like ZnO particles were synthesized by adding surfactant CTAB to the reactive system. The obtained samples were investigated by XRD and TEM. The results indicated that the products belong to the Wurtzite Group with a hexagonal phase. CTAB plays an important role in the process of rod-like ZnO particles formation and the morphology of nano-ZnO can be controlled by the quantities of CTAB. The growth mechanism and reason were also discussed briefly.
