ZnO nanostructures, including nanotowers, nanovolcanoes, nanorods, nanotubes, and nanoflowers, have been grown by using the hydrothermal technique. Most of the ZnO nanostructures show the perfect hexagonal cross section and well-faceted top and side surfaces. The basic chemistry and growth mechanism are discussed. By increasing the reaction time, the volcano-like and tube-like ZnO structures were formed due to the Ostwald ripening process and the selective adsorption of the complexes. By using the seed layer, the dense-arrayed, regular oriented ZnO nanorods were obtained due to the decreased nucleation barrier and the abundant interfaces as well as the increasing surface roughness.
通过水热技术生长出了氧化锌纳米结构，包括纳米塔、纳米火山、纳米棒、纳米管和纳米花。大多数氧化锌纳米结构呈现出完美的六边形横截面以及顶面和侧面的良好晶面。讨论了其基本化学性质和生长机制。通过延长反应时间，由于奥斯特瓦尔德熟化过程和配合物的选择性吸附，形成了火山状和管状的氧化锌结构。通过使用籽晶层，由于成核势垒降低、界面丰富以及表面粗糙度增加，获得了密集排列、取向规则的氧化锌纳米棒。
