Microporous zeolites have proven to be of great importance in many chemical processes. Yet, they often suffer from diffusion limitations causing inefficient use of the available catalytically active sites. To address this problem, hierarchical zeolites have been developed, which extensively improve the catalytic performance. There is a multitude of recent literature describing synthesis of and catalysis with these hierarchical zeolites. This review attempts to organize and overview this literature (of the last 5 years), with emphasis on the most important advances with regard to synthesis and application of such zeolites. Special attention is paid to the most common and important 10- and 12-membered ring zeolites (MTT, TON, FER, MFI, MOR, FAU, and *BEA). In contrast to previous reviews, the research per zeolite topology is brought together and discussed here. This allows the reader to instantly find the best synthesis method in accordance to the desired zeolite properties. A summarizing graph is made available to enable the reader to select suitable synthesis procedures based on zeolite acidity and mesoporosity, the two most important tunable properties.
微孔沸石已被证明在许多化学过程中具有重要意义。然而,它们常常受到扩散限制,导致可用催化活性位点的利用效率低下。为了解决这个问题,人们开发了多级孔沸石,其显著提高了催化性能。最近有大量文献描述了这些多级孔沸石的合成及其催化作用。本综述试图整理和概述这些文献(过去5年的),重点关注此类沸石在合成和应用方面的最重要进展。特别关注最常见且重要的具有10元和12元环的沸石(MTT、TON、FER、MFI、MOR、FAU和*BEA)。与以往的综述不同,这里将按每种沸石拓扑结构的研究汇总并进行讨论。这使读者能够根据所需的沸石性质立即找到最佳合成方法。提供了一个总结图表,以便读者根据沸石酸度和介孔率这两个最重要的可调性质选择合适的合成程序。
