摘要:

沸石分子筛是一类重要的具有明确孔道结构以及催化位点的结晶孔材料. 但是由于其微孔开口的本质限制了其在大分子吸附与转化方面的应用. 10年前, 西班牙ITQ研究所的Corma教授、 吉林大学于吉红教授以及本文通讯作者发表了一篇关于超大孔分子筛的历史回顾文章. 该文从超大孔分子筛的合成、 结构、 假想结构以及催化性能等方面进行了综述. 这一类材料填补了传统沸石分子筛和有序介孔材料之间的孔径缺口. 在最近10年中, 多种新型超大孔分子筛以及新颖的合成方法陆续被报道. 本文对该方向近10年中的研究进行了综合评述.

Abstract:

Zeolites are a vital type of crystalline material with well-defined channel structures and isolated catalytically active sites. However, their microporous nature hinders their applications in the transformation of bulky molecules. Ten years ago, Corma and coworkers provided a historical review of the synthesis, structure, and catalytic performance of extra-large pore(ELP) zeolites. This type of zeolite bridges the gap between traditional zeolites and ordered mesoporous materials. In the last decade, several new ELP zeolites, as well as novel methodologies for preparing them, have been reported. This review provides a renewed view of this topic.

Key words: Extra-large pore, Zeolite, Organic structure directing agent, Topotactic transformation, Assembly-disassembly-organization-reassembly(ADOR)
