中文摘要：

利用β沸石纳米簇和曲拉通TX-100分别作为骨架构筑前驱物和孔道导向剂，在酸性介质中通过（N°H＋）Cl-S＋组装机制合成了蠕虫状孔道排列的A1MSU介孔材料，并借助测试手段对其进行了系统表征。结果表明：制备体系盐酸浓度对A1MSU的结构性能、骨架组成及收率有着显著影响。介质酸浓度较低（〈0．5mol／L）时所得Al-MSU的物化性质较差，而且产物收率低（基于样品粉末质量）；而体系酸浓度大于2．5mol／L时将造成部分铝原子从骨架中析出，导致最终产物中铝元素含量显著降低。基于结构性能、骨架组成和样品收率等综合因素，体系酸浓度介于1．5—2．0mol／L时是合成AlMSU介孔材料的合适区间。

英文摘要：

A series of AlMSU mesostructures with wormhole frameworks have been successfully synthesized using pre-assembled zeolite nanoclusters and nonionic TX-100 as the inorganic precursor and structure-directing agent, respectively, under acidic conditions. It was shown that, on the basis of careful structural characterization, the acidity of the synthesis medium had a significant impact on the textural characteristics, framework composition and yield of the final mesostructure. Low-quality A1MSU was obtained when the acid concentration was low （about 0, 5 tool/L）. In contrast, most of the beta zeolite nanoclusters were destroyed during the self-assembly process under extremely acidic conditions （e. g. , 3.0 mol/L）. Therefore, an optimal acid concentration between 1.5 and 2.0 mol/L is advantageous during the synthesis of AIMSU.
