烷基胺插层层状化合物LiNbWO_6纳米复合材料的研究

Synthesis and Characterization of Nanocomposite Material Alkylamine Intercalated into Layered Compound LiNbWO_6

LiNbWO6作为一种无机层状化合物,是制备有机-无机物纳米复合材料的优良基体。使用高温固相方法合成LiNbWO6,并用直接插入法分别将正丙胺、正丁胺、正己胺、正辛胺插入HNbWO6层间制备了烷基胺的插层复合材料,并用SEM,XRD等方法进行了表征,同时研究了层间距的增加与烷基胺中碳原子数目之间的关系。

LiNbWO6 is a well-defined layered inorganic material and an excellent base to prepare organic-inorganic nanocomposites. In this paper,LiNbWO6 microcrystalline were prepared by means of high temperature solid state synthesis method,and then n-propylamine,n-butylamine,n-hexylamine and n-octylamine were directly intercalated into the HNbWO6 layers to fabricate alkylamine nanocomposite by the guest-guest ion exchange method. The structure and the morphology of the nanocompostive were characterized by scanning electronic microscopy （SEM） and X-ray diffraction （XRD）. Moreover,the relation of the interlayer distance of intercalates and the number of carbon atoms in alkylamine was investigated systematically.
