通过调节水与甲醇的比例，采用温和、简单的溶液法制备了氧化锌纳米线、纳米棒和纳米颗粒。用原子力显微镜和X射线光电子能谱对所制备的氧化锌纳米结构进行了表征。随着水/醇比的增加，氧化锌纳米结构的形态发生变化，从致密的纳米线到稀疏的纳米线，再到纳米棒，再到纳米颗粒。水与甲醇的比例在氧化锌纳米结构的形成中起着重要的作用。其形成机制与化学势有关，化学势与它们的表面积比成正比。
ZnO nanowires, nanorods and nanoparticles through modulating the ratio of water to methanol have been synthesized by using a mild and simple solution method. The as-prepared ZnO nanostructures have been characterized by atomic force microscopy and X-ray photoelectron spectroscopy. With the increase of the ratio of water to methanol, the morphology of ZnO nanostructures varied form denser nanowires, to sparse nanowires, to nanorods, and then to nanoparticles. The ratio of water to methanol is supposed to play an important role in the formation of ZnO nanostructures. The mechanism of formation is related to the chemical potential, which is simply proportional to their surface ratio.
