摘　　要：在氩气保护气氛下利用商用三氧化钼粉与硫进行气相反应,通过对气相反应条件的合理控制,制备出了可工业化大量生产的高纯度富勒烯结构二硫化钼,其平均粒径范围在200nm以内。并讨论了制备高纯富勒烯结构二硫化钼的逐步反应模型和反应条件对MoS2形貌的影响。样品经由XRD、SEM、HRTEM进行表征。Inorganic fullerene-like MoS2 nano-spheres were obtained by the reaction of commercial MoO3 powder and S in argon atmosphere under well-controlled conditions. The average diameter size of the nano-particles is between 100 and 200 nm. The shape of MoSz is decided by reaction temperature and the flow regime. The growth mechanism was proposed for the formation of these nano-particles. IF-MoS2 nano-particles were characterized by X-ray diffraction, scanning electron microscope and HRTEM.
