讨论了制备具有低骨架密度和超大孔的沸石所需的条件。提出了框架稳定性与几何和拓扑描述符之间的相关性。从合成机理、有机结构导向剂（OSDA）的导向作用、骨架原子和凝胶浓度等方面对超大孔沸石的合成进行了合理化尝试。超大孔沸石，包括最近发现的手性介孔ITQ-37，描述和它们的催化和吸附性能进行了讨论。最后，提出了用于制备具有不同孔拓扑结构的超大孔沸石的策略，这些超大孔沸石可以实现预先确定的催化和吸附目标。
The conditions required to produce zeolites with low framework density and extra‐large pores are discussed. Correlations between framework stability and geometrical and topological descriptors are presented. An attempt has been made to rationalize the synthesis of extra‐large‐pore zeolites in terms of the synthesis mechanism, the directing effect of the organic structure directing agent (OSDA), the framework atoms, and the gel concentration. Extra‐large‐pore zeolites, including the recently discovered chiral mesoporous ITQ‐37, are described and their catalytic and adsorption properties discussed. Finally, strategies are presented for the preparation of extra‐large‐pore zeolites with different pore topologies that can fulfill pre‐established catalytic and adsorption targets.
