    Preparation of MoS2 Nanorods by Liquid Phase Reduction Method

      摘要
    • 摘要: 在低温条件下,以十二烷基苯磺酸钠(SDBS)和聚乙二醇(PEG)为表面活性剂,采用液相还原法制备了MoS2纳米杆,用XRD、EDS、IR和TEM等方法对产物进行了表征;并对MoS2纳米杆的反应机理、生长机制以及表面活性剂的形貌调控作用进行了分析.结果表明:制备的MoS2纳米杆形貌均匀规则,直径约30 nm,长度约400 nm,而且表面被PEG和SDBS所修饰;提出了基于SDBS和PEG复配作用的基体包覆-模板定向的生长模型.

       

      Abstract: MoS2 nanorods were successfully prepared by liquid phase reduction method with sodium dodecyl benzene sulfonate(SDBS) and polyethylene glycol(PEG) as surfactants at low temperature.The microstructure and chemical compositions of the as-obtained samples were studied by X-ray diffraction (XRD),infrared spectrum (IR) and transmission electron microscopy(TEM)equiped with EDAX energy dispersive X-ray spectrometer analysis (EDS).It has been found that the MoS2 nanorods had a perfect rod-like shape with length of 400 nm and diameter of 30 nm,and modified by PEG and SDBS.As a result of the synergistic effect between SDBS and PEG,a template-oriented growth mechanism on coated matrix was proposed.
