华东师范大学化学与分子工程学院吴鹏团队开发了用于选择性催化的“开放”无孔Nonasil沸石结构。相关研究成果发表在2021年11月23日出版的《美国化学会杂志》。

Nonasil（NON-type framework）沸石具有大的内笼，但只有6环（R）孔径，被认为是一种无孔材料，没有作为催化剂或吸附剂的实际应用价值。

该文提出了一种新的自底向上的结构构建策略，辅以设计良好的双子型表面活性剂，以“打开”非笼状结构，构建两个具有可接近和稳定酸位的新型NON-相关结构。所得衍生物（命名为ECNU-27）具有分级孔隙率、短程有序的8-R微孔和丰富的晶间介孔，是1-丁烯裂解制低碳烯烃的理想催化剂。

Abstract: Nonasil (NON-type framework) zeolite, having inner large cages but only 6-ring (R) apertures, is recognized as a nonporous material without practical application values as catalysts or adsorbents. A novel bottom-up structural construction strategy assisted with well-designed Gemini-type surfactant is proposed to “open” the non cages, constructing two novel NON-related structures with accessible and stable acid sites. The obtained derivant (named as ECNU-27) possessed hierarchical porosity with short-range ordered 8-R micropores and abundant intercrystal mesopores, serving as a promising catalyst for the 1-butene cracking to lower alkenes.
