Hierarchical zeolites combine the intrinsic catalytic properties of microporous zeolites and the enhanced access and transport of the additional meso- and/or macroporous system. These materials are the most desirable catalysts and sorbents for industry and become a highly evolving field of important current interests. In addition to the enhanced mass transfer leading to high activity, selectivity, and cycle time, another essential merit of the hierarchical structure in zeolite materials is that it can significantly improve the utilization effectiveness of zeolite materials resulting in the minimum energy, time, and raw materials consumption. Substantial progress has been made in the synthesis, characterization, and application of hierarchical zeolites. Herein, we provide an overview of recent achievements in the field, highlighting the significant progress in the past decade on the development of novel and remarkable strategies to create an additional pore system in zeolites. The most innovative synthesis approaches are reviewed according to the principle, versatility, effectiveness, and degree of reality while establishing a firm link between the preparation route and the resultant hierarchical pore quality in zeolites. Zeolites with different hierarchically porous structures, i.e., micro-mesoporous structure, micro-macroporous structure, and micro-meso-macroporous structure, are then analyzed in detail with concrete examples to illustrate their benefits and their fabrications. The significantly improved performances in catalytic, environmental, and biological applications resulting from enhanced mass transport properties are discussed through a series of representative cases. In the concluding part, we envision the emergence of “material-properties-by-quantitative and real rational design” based on the “generalized Murray’s Law” that enables the predictable and controlled productions of bioinspired hierarchically structured zeolites. This Review is expected to attract important interests from catalysis, separation, environment, advanced materials, and chemical engineering fields as well as biomedicine for artificial organ and drug delivery systems.

分级结构沸石:从设计到应用。

分级沸石结合了微孔沸石的内在催化特性和额外的中孔和/或大孔系统的增强进入和传输。这些材料是工业上最理想的催化剂和吸附剂,并成为当前重要利益的高度发展领域。除了增强的传质导致高活性、选择性和循环时间之外,沸石材料中分级结构的另一个重要优点是它可以显着提高沸石材料的利用效率,从而使能量、时间和原料达到最小。材料消耗。分级沸石的合成、表征和应用取得了实质性进展。在此,我们概述了该领域的最新成就,强调在过去十年中在开发新颖和卓越的策略以在沸石中创建额外的孔隙系统方面取得的重大进展。根据原理、通用性、有效性和现实程度对最具创新性的合成方法进行了审查,同时在制备路线和所得沸石分级孔隙质量之间建立了牢固的联系。然后通过具体实例详细分析具有不同分级多孔结构(即微介孔结构、微-大孔结构和微-介孔-大孔结构)的沸石,以说明其优点和制备方法。在催化、环境、通过一系列有代表性的案例讨论了由增强的传质特性产生的生物应用。在结论部分,我们设想了基于“广义默里定律”的“材料性质由定量和真正合理的设计”的出现,它能够实现仿生分层结构沸石的可预测和可控生产。该综述有望吸引催化、分离、环境、先进材料和化学工程领域以及人工器官和药物输送系统的生物医学领域的重要兴趣。我们设想了基于“广义默里定律”的“定量和真正理性设计的材料特性”的出现,它能够实现仿生分层结构沸石的可预测和可控生产。该综述有望吸引催化、分离、环境、先进材料和化学工程领域以及人工器官和药物输送系统的生物医学领域的重要兴趣。我们设想了基于“广义默里定律”的“定量和真正理性设计的材料特性”的出现,它能够实现仿生分层结构沸石的可预测和可控生产。该综述有望吸引催化、分离、环境、先进材料和化学工程领域以及人工器官和药物输送系统的生物医学领域的重要兴趣。
