摘　　要：在水和乙醇组成的二元体系中,以CuCl2为铜源,尿素为沉淀剂,分别以聚乙二醇(PEG)和醋酸钠(NaAC)为形貌控制剂,利用水热法可控合成了微球氧化铜和虾形花盘状氧化铜。采用X射线衍射(XRD)、扫描电镜分析(SEM)、能谱分析等方法对产物进行结构分析和表征。以花盘状氧化铜为例,通过时间实验,研究了其生长过程,提出了可能的形成机理。Microsphere like and shrimp shape disk like CuO were synthesized by the hydrothermal meth- od in the C2H5OH--H2O solvent by using CuCl2 as the copper source, CO（NH2）2 as a precipitation a- gent, and PEG and NaAc as morphology control agents respectively. The as--prepared products were characterized and analyzed by means ofX--ray diffraetion （XRD）, scanning electron microscopy （SEM） and energy spectra. The formation process of disk--like CuO was studied by the time experi- ment, and the possible formation mechanism was proposed.
