Hierarchical zeolites containing both microporosity and meso/macroporosity have emerged as a new and important branch of zeolites due to their potential for improving mass transfer and molecular accessibility, which are key to overcoming steric, diffusional, and coke-formation limitations in catalytic reactions. In this review, we present significant recent progress in the fabrication of hierarchical zeolites via mesoporogen, mesoporogen-free, and demetallization strategies and discuss the advantages and disadvantages of each method. The impact of the hierarchical structures of zeolites (e.g., CHA, FAU) on their enhanced catalytic activity and product selectivity is highlighted. Finally, we address the current challenges and future perspectives for the designed construction of hierarchical zeolite catalysts to meet the increasing demands for industrial catalytic applications.

含有微孔度和介孔/大孔度的层状沸石由于它们具有改善传质和分子可及性的潜力而成为沸石的新的重要分支，这是克服催化反应中空间，扩散和焦炭形成限制的关键。在这篇综述中，我们介绍了通过介孔原，无介孔原和脱金属策略制备分级沸石的最新进展，并讨论了每种方法的优缺点。沸石的分层结构（例如CHA，FAU）的影响）增强了它们的催化活性和产物选择性。最后，我们解决了分层沸石催化剂设计结构的当前挑战和未来展望，以满足对工业催化应用不断增长的需求。
