三氧化钼/苯胺层状复合材料的制备

以三氧化钼为无机主体, 用十二烷基胺对三氧化钼层间进行改性, 成功地制备了三氧化钼/苯胺层状复合材料. X射线衍射、元素分析、扫描电子显微镜、红外光谱测试及差热分析结果表明, 苯胺分子已成功地插入三氧化钼层间, 所得复合物化学式为ANI]0.4MoO3. 插层后, 三氧化钼仍保持规则有序的层状结构, 其层间距扩大至1.318 nm. 讨论了无机主体与有机客体之间的相互作用、苯胺在层间的可能排布形式以及苯胺插入层间的反应机理.

Preparation of MoO3/Aniline Layered Composite Material

Molybdenum oxide/aniline composite material with layered structure of ANI]0.4MoO3 was prepared indirectly with molybdenum oxide/dodecylamine as the starting material. This composite was characterized via powder X-ray diffraction,scanning electron microscopy,elemental analysis,infrared spectroscopy and thermal analysis. The results show that the intercalation of aniline successfully proceeds in the present process. The layered morphology of the parent oxide is maintained. The intercalated ANI expanded the interlayer spacing of MoO3 from 0.692 nm to 1.318 nm with the gallery height 0.626 nm. A possible arrangement of intercalated aniline in the gallery of MoO3 was proposed. The interaction between the inorganic host and the organic guest was discussed. The intercalation mechanism of aniline was also discussed.
