本文以钼酸钠、硫代乙酰胺为前驱体, 硅钨酸为添加剂, 成功用水热法合成高纯度纳米花状二硫化钼. 产物特性用X射线衍射(XRD)、能量色散谱(EDS)、扫描电子显微镜(SEM)进行表征. XRD和EDS图显示实验产物为二硫化钼, 且其结晶度和层状堆垛良好. SEM图谱则表明二硫化钼为纳米花状结构, 颗粒直径300 nm左右, 由几十上百片花瓣组成, 每片花瓣厚度十个纳米左右. 通过以硅钨酸为变量的梯度实验, 研究发现, 硅钨酸对于纳米花状MoS2的形成具有重要作用, 不添加硅钨酸, 无法形成纳米花状MoS2, 此外, 硅钨酸的剂量会影响合成MoS2的大小和形貌. 本文还对纳米花状二硫化钼的形成机理做了初步的讨论.High-purity flower-like MoS2 microspheres have been successfully synthesized by hydrothermal method using Na2MoO4 and CH3CSNH2 as precursors, and H4O40SiW12 as an additive. Samples are characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectrometer (EDS). XRD and EDS patterns show that the as-prepared samples are MoS2, which have good crystallinity with a well-stacked layered structure. SEM images show that the as-prepared MoS2 are composed of flower-like microspheres with a mean diameter about 300 nm, the structures of which are constructed from dozens of hundreds of MoS2 nano-sheet with a thickness of several nanometers. It is also found that the silicotungstic acid plays an important role in the formation of the flower-like MoS2 microspheres, which could affect the size and morphology of the MoS2. Flower-like MoS2 is not found in the as-prepared product without adding silicotungstic acid. A formation mechanism of MoS2 microspheres is tentatively given.
