摘　　要：以聚乙二醇(PEG)为模板剂,采用软模板法制备出MoS2空心微球,并采用X射线衍射仪(XRD)、红外光谱仪(IR)和扫描电子显微镜(SEM)对产物进行表征.结果表明,所制备的MoS2为粒径约2-7μm的空心微球,但结晶程度较差,需通过退火工艺进行改善;聚乙二醇与MoS2发生了较为强烈的有机-无机杂化作用,其浓度和分子量对产物形貌调控均有重要影响.同时,结合红外光谱分析,对MoS2空心微球的形成机理进行了初步的探讨.Hollow MoSs microspheres were synthesized via soft template method with polyethylene glycol （PEG） as template. The as-prepared samples were characterized with X-ray diffraction （XRD）, infrared spectrometer （IR）, and scanning electron microscopy （SEM）. The results indicated that the as-prepared MoS2 was hollow microspheres with diameter of 2-7 μm and had poor crystallinity, which could be improved by calcination. There was strong organicinorganic hybridization between polyethylene glycol and MoS2. Furthermore, both the concentration and molecular weight of polyethylene glycol had great effects on morphological control of the product. Based on the IR analysis of product, the formation mechanism of hollow MoS2 microspheres was discussed preliminarily.
