Constructing superstructured crystalline materials by crystal engineering is an attractive objective for miscellaneous fields of researchers spanning biomimetics to catalytic materials. Zeolite is a kind of important crystalline catalyst, and superstructured zeolite has great potential for widespread applications. However, the ambiguous crystallization mechanisms hamper the effective and scientific fabrication of superstructured zeolite with exceptional properties. Herein, a fractal superstructured MTW zeolite with mesocrystal side branches is prepared via a nanoparticle-based nonclassical pathway with twinning-plane induced crystallization, which is distinct from the formation of general mesocrystal via crystal–crystal oriented attachment. Deformed atomic connection at a specific crystallographic plane contributes to the production of side branches. Moreover, this intriguing morphology could be regulated merely via adjusting the crystallization kinetics based on the unequivocal nonclassical crystallization mechanism. It will open a new avenue for design and synthesis of targeted crystals with superstructure and extraordinary properties.

工程分形MTW沸石中晶：通过孪晶面诱导结晶的基于粒子的树枝状生长
通过晶体工程构造超结构晶体材料是研究人员的一个吸引人的目标，该领域涉及从仿生物到催化材料的研究。沸石是一种重要的晶体催化剂，超结构沸石具有广阔的应用前景。然而，模棱两可的结晶机制阻碍了具有优异性能的超结构沸石的有效和科学制造。在此，通过具有孪晶面诱导结晶的基于纳米颗粒的非经典途径，制备了具有介晶侧分支的分形超结构MTW沸石，这与通过晶体-晶体取向的附着形成普通的介晶不同。在特定的晶体平面上变形的原子连接有助于产生支链。而且，仅通过基于明确的非经典结晶机理调节结晶动力学就可以调节这种有趣的形态。这将为具有超结构和非凡性能的目标晶体的设计和合成开辟一条新途径。
