在130 ℃, 以水和乙二醇混合体系为溶剂, 无水硫酸铜和硫脲反应, 制备了不同物相结构和形貌的铜的硫化物. 通过扫描电镜(SEM)、透射电镜(TEM)、电子衍射(SAED)及X射线衍射(XRD)等技术, 对所得产物进行了表征. 结果表明, 溶剂中水含量的变化对铜的硫化物的物相影响不明显, 但显著影响其形貌; 反应时间对其物相和形貌都产生影响. 并对其形成机理进行了探讨.

关键词: 铜的硫化物, 水, 乙二醇, 形貌, 物相结构

Copper sulfides, such as Cu1.8S and Cu7S4, in the wire-like and ball-like shapes congregated from nano-spherical particles and nanoslices have been prepared by a solvothermal method without using any surfactants. The products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and the selected area electron diffraction techniques. A systematic investigation has been carried out to understand the factors, such as the systematic composition of the mixture solvent and the reaction time, influencing the structure bulky phase and the morphology of the samples. The results showed that the water content in the solvent affected the morphology of the samples, and the reaction time affected both the crystal structure and morphology. Possi-ble crystal growth process was also discussed.

Key words: copper sulfide, water, ethyleneglycol, morphology, phase structure
