摘　　要：利用无机钼源和有机硫源作为原料,在表面活性剂的结构导向及超声波辅助下,通过水热法合成了纳米二硫化钼。采用X射线衍射、傅立叶红外光谱、透射电镜对其进行了表征,从微观结构理论的角度分析了CTAB的加入对反应过程和产物的影响。结果表明:CTAB的加入不仅可以有效地阻止产物微粒的团聚,还能够控制产物的形貌及物相,并且无需惰性气体保护的高温煅烧,即可在较低水热温度下直接获得粒径为10～20nm、六方晶相的超细2H-MoS2。Nano-sized molybdeum disulfide is prepared by hydrothermal method via surfactant and ultrasonic assistance,using sodium molybdate and thiourea as reagents.As-synthesized MoS2 samples were characterized by X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FT-IR),and transmission electron microscope (TEM).The effects of addition of CTAB on reaction process and resulted particles have been analyzed by microstructure theory.It has been shown that the addition of CTAB can not only prevent the agglomeration of the resulting particles,but regulate their morphologies and phase compositions.The resulting 2H-MoS2 with hexagonal phase and average size of 10~20 nm can be directly obtained at low hydrothermal temperature needless of high-temperature sintering under inert gas protection.
