采用乙二醇（EG）辅助水热法合成了树枝状CuO纳米结构，其结构由棒状主干和一些棒状分支组成。X射线衍射（XRD）和选区电子衍射（SAED）结果表明，树枝状CuO纳米结构为单斜相，单个分支为单晶。研究了温度、pH值等生长条件对CuO形貌和结构的影响。结果表明，不同的温度和pH值会导致CuO的形貌和结构发生变化。初步提出了CuO形貌和结构演化的可能机制。
The dendrite-like CuO nanostructures, consisting of a rod-like main stem and some rod-like sub-branches, have been synthesized by a simple ethylene glycol (EG) assisted hydrothermal method. The X-ray diffraction (XRD) and the selected area electron diffraction (SAED) patterns indicate that the dendrite-like CuO nanostructures are of monoclinic phase and the individual branch of CuO is single crystalline in nature. The effects of the growth conditions such as temperature and pH value on the morphology and structures of CuO have also been investigated. It is indicated that different temperature and pH value result in the morphology and structure evolution of CuO. Moreover, a possible mechanism for the morphology and structures evolution of CuO has been primarily presented.
