液相还原法制备MoS2纳米杆
Preparation of MoS2 Nanorods by Liquid Phase Reduction Method
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.
