摘要:

将表面活性剂与微孔分子筛的纳米团簇进行组装的方法实现了介孔分子筛孔壁的部分晶化,可以大幅提高介孔分子筛的水热稳定性,但是较高的模板剂和水用量导致的较高合成成本限制了其进一步应用。本文结合低成本合成高稳定性介孔分子筛及其工业应用的研究历程,综述了在合成高稳定性介孔分子筛的同时降低有机模板剂和水的用量方面的研究进展,包括晶种协同作用法、母液循环法、亲水物质的引入法和复合模板剂法等,阐述了各种方法的合成机理和各自的优缺点,并指出在无有机模板剂条件下得到全结晶孔壁的介孔分子筛是未来的发展方向。

Abstract:

Hydrothermally stable mesoporous aluminosilicates (MAs) could be obtained via self-assembly of clusters of primary and secondary building units of microporous zeolites. However, high consumption of water and organic template hinder its industrial application. To solve this problem, hydrothermally stable MAs was proposed via the introduction of microporous precursor into the wall of mesophase. Based on the development process of microporous zeolite precursor assembly method, various strategies to decrease the consumption of organic template and water were summarized, including seed-assisted method, mother liquid recycling strategy, introduction of hydrophilic materials, and composite templates method. Based on the analysis of their advantages and disadvantages, future development directions are pointed out. Specifically, the MAs with fully crystallized walls of mesophase without organic template will be the research focus.

Key words: mesoporous aluminosilicate, hydrothermal stability, low template consumption, low water consumption, low-cost synthesis
