The formation of mesopores in microporous zeolites is generally performed by postsynthesis acid, basic, and steam treatments. The hierarchical pore systems thus formed allow better adsorption, diffusion, and reactivity of these materials. By combining organic and inorganic structure-directing agents and high-throughput methodologies, we were able to synthesize a zeolite with a hierarchical system of micropores and mesopores, with channel openings delimited by 28 tetrahedral atoms. Its complex crystalline structure was solved with the use of automated diffraction tomography.
中孔在微孔沸石中的形成通常通过后合成酸、碱和蒸汽处理来完成。由此形成的分级孔系统允许这些材料具有更好的吸附、扩散和反应性能。通过结合有机和无机结构导向剂和高通量方法，我们能够合成一种具有微孔和介孔分级体系的沸石，其通道开口由 28 个四面体原子限定。其复杂的晶体结构通过使用自动衍射层析技术得到解决。
