摘要

Hollow molybdenum disulfide (MoS_2) microspheres were synthesized in ionic liquids (1-butyl-3-methylimidazolium chloride, [BMIM]Cl)/water binary emulsions by the hydrothermal method at 180 ℃ for 24 h. The optimum value of volumetric proportions (ILs/water) equaled 1:9. The structure and morphology of products were characterized by means of X-ray powder diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM). The experimental results gave the evidences that the sample is consists of hollow spheres 1.8 - 2.1 μm in diameter, and there are much sheet-like structures on the surface of hollow MoS_2 microspheres. In addition, ILs could be collected and reused for subsequent reactions.
