摘要： 在水热体系下，通过表面活性剂和分子筛导向剂共同反应制备规则的纳米层状分子筛，实验结果表明，十六烷基三甲基溴化铵在水中达到一定浓度后就会自组装成层状胶束，再加入分子筛导向剂在一定条件下即可合成纳米层状分子筛。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和固体核磁(NMR)表征可以证明所得的样品为20nm左右的层状微孔分子筛，样品具有均匀的层状形貌和规则的微孔结构。

Abstract: High ordered nano-lamellar molecular sieves have been prepared by a co-assembly process of surfactant and structure-directing agent in an hydrothermal system. Experimental data have demonstrated that CTAB can form lamellar micelle by the self-assembly when its concentration in aqueous solution achieves CMC level, leading to the formation of nano-lamellar molecular sieves. The products have homogeneous flaky morphology with a dimension of about 20 nm and possess high ordered microporous structures.

Key words: Nanometer, Lamellar aluminosilicate, Microporous molecular sieve
