Abstract: Hollow MoS2 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 organic-inorganic 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 mechanismof hollow MoS2 microspheres was discussed preliminarily.
