摘要
以氯化铜和碳酸钠为原料在140℃水热反应12 h,通过改变反应溶剂,可控合成CuO微/纳米结构材料。采用X射线衍射仪(XRD)、扫描电镜(SEM)、透射电镜(TEM)和红外分光计(FT-IR)对产物的物相组成、微观形貌和红外性质进行表征,并探讨CuO的生长机理。结果表明:通过改变反应溶剂,可实现CuO微/纳米形貌的调控。在纯水,水/乙醇,水/乙二醇的溶剂中,产物的形貌分别为大尺寸的花状团簇,小尺寸的花球,尺寸均匀的球形小颗粒,得到的CuO是单斜相结构,且产物主要为CuO。花状团簇,花球以及球形颗粒3种形貌的平均晶粒尺寸分别约为32 nm,28 nm和25 nm。
Micro/nano structure CuO materials were controllable synthesised via hydrothermal method at 140℃for 12 h using copper chloride and sodium carbonate as raw materials. Different CuO micro/nano structures were obtained by changing the reaction solvent. The phase composition, microstructure and infrared properties of product were characterized by XRD, SEM, TEM and FT-IR, respectively, and the growth mechanism of the CuO was also discussed. The results show that, the morphology of micro/nano CuO can be controlled by changing the reaction solvent. The morphologies of the products are large size of flower clusters, small size flower sphere, uniform spherical particles in pure water, ethanol, water/ethylene glycol solvent, respectively. The products are mainly monoclinic phase structure CuO. The average grain size of the flower clusters, flower sphere and spherical particles are about 32 nm, 28 nm and 25 nm, respectively.
