用户论文(2005)：纳米二硫化钼的制备及AFM表征

【中文摘要】 利用硫化铵与钼酸铵为反应物,在适宜的分散剂与超声帮助下,通过快速液相沉淀法制备出三硫化钼,再通入高纯氢气,将三硫化钼加热分解,制备出二硫化钼。X射线衍射结果表明获得的三硫化钼是典型的非晶态MoS3,二硫化钼为2H-MoS2;通过原子力显微镜发现,制备的二硫化钼的平均粒径为70nm左右。 【英文摘要】 Molybdenum trisulfide is first obtained by the fast reaction of ammonium sulfide and ammonium molybdate with ultrasonication and a proper dispersant.Then molybdenum disulfide is prepared under H_(2) from the resulted molybdenum trisulfide.The results of XRD indicate that the obtained MoS_(3) is noncrystalline and MoS_(2) particles are of 2H-MoS_(2) characters.The pictures of AFM show the average size of the resulted maximal MoS_(2) particles is about 70nm.
