Zeolites with extra‐large pores have attracted great attention because of their important applications such as in hydrocracking, catalysis, and separation of large molecules. Despite much progress has been made during the past decades, the synthesis of these materials remains a big challenge. A new extra‐large‐pore zeolite NUD‐1 (Nanjing University Du’s group zeolite no. 1) is synthesized by using an approach based on supramolecular self‐assemblies of small aromatic organic cations as structure‐directing agents. NUD‐1 possesses interconnecting 18‐, 12‐, and 10‐membered ring channels, built from the same building units as those of ITQ‐33 and ITQ‐44. There coexist single 3‐membered ring, double‐3‐membered ring and double‐4‐membered ring secondary building units in NUD‐1, which have not been seen in any other zeolites.

带有相交的18、12和10圆环通道的超大孔径沸石

具有大孔的沸石因其在加氢裂化，催化和分离大分子等方面的重要应用而备受关注。尽管在过去的几十年中已经取得了很大的进步，但是这些材料的合成仍然是一个巨大的挑战。一种新的超大孔沸石NUD-1（南京大学杜氏集团的1号沸石）是采用一种基于小的芳香族有机阳离子的超分子自组装作为结构导向剂的方法合成的。NUD-1拥有互连的18、12和10员环形通道，它们的建造单元与ITQ-33和ITQ-44相同。在NUD-1中存在单3元环，双3元环和双4元环二级建筑单元，这在任何其他沸石中都没有发现。
