摘要： 利用钨酸钠与表面活性剂十六烷基三甲基溴化铵(CTAB)及硫代乙酰胺在水热条件下合成了一种中介结构层状硫化钨WS-L.通过化学及元素分析、红外光谱、光电子能谱、粉末X射线衍射、透射电镜、扫描电镜以及热重分析等方法进行表征.WS-L的化学式为WS3.5·[C16H33N(CH3)3]2,其中硫化钨所带负电荷被嵌插在层间的表面活性剂阳离子所平衡.

Abstract: Anew tungsten sulfide(designated as WS-L) with intercalated cetyltrimethylammonium surfactant cations was prepared under a mild hydrothermal condition, and the product was characterized by IR, ICP, SEM, TEM, XPSand TGA. Sodium tungstate and thioacetamide were used as the tungsten and sulfur sources respectively, whereas the template was cetyltrimethylammonium bromide. XRDand TEMresults reveal that the compound has a lamellar mesostructure with an interlayer distance of 2.925 nm. The empirical composition of the individual inorganic layer is [WS3.5]2-and the negative charges on the layer are balanced by the surfactant cations intercalated between two adjacent layers.

Key words: Mesostructure lamellar, Tungsten sulfide, Hydrothermal synthesis, Characterization
