Special Issue Information

Dear Colleagues,

Zeolites and zeolite-based materials are versatile catalysts for a wide range of important transformations in both current and future chemical industries. Owing to their strong Brønsted/Lewis stability, high (hydro-)thermal stability, shape selectivity, and confinement properties, zeolites are unique catalytic materials. Recent developments in the rational design and fabrication of advanced zeolites and zeolite-based composites have significantly expanded the scope of synthetically available structures. Further breakthroughs in this direction are hardly possible without a deep understanding of the corresponding structure–activity, structure–selectivity, and structure–stability relationships. Fundamental molecular insights into zeolite growth, confinement effects, and modes of catalytic action of zeolite materials will undoubtedly lead to more active, selective, and stable catalysts. The development of novel characterization techniques and their combinations, as well as operando spectroscopy studies will clearly play a crucial role in the further progress of zeolite catalysis.

The aim of this Special Issue is to highlight promising research on zeolite catalysis, including conventional catalysis, photocatalysis, electrocatalysis, and plasma catalysis. Special attention will be paid to articles (i) linking the physico-chemical properties of zeolite-based materials with their catalytic action; (ii) employing novel characterization strategies to deepen the understanding of the existing catalytic systems; (iii) utilizing the fundamental understanding of zeolite materials for the rational design of improved catalysts; and (iv) unravelling the mechanistic pathways of zeolite catalysis.

Abstract

Zeolites are promising catalysts that are widely used in petrochemical, oil, and gas industries due to their unique characteristics, such as ordered microporous networks, good hydrothermal stability, large surface area, tunable acidity, and shape-selectivity. Nevertheless, the sole presence of microporous channels in zeolites inevitably restricts the diffusion of bulky reactants and products into and out of the microporous networks, leading to retarded reaction rates or catalyst deactivation. This problem can be overcome by developing hierarchical zeolites which involve mesoporous and macroporous networks. The meso- and macro-porosities can enhance the mass transport of molecules and simultaneously maintain the intrinsic shape selectivity of zeolite microporosity. Hierarchical zeolites are mainly developed through post-synthesis and pre-synthesis or in situ modification of zeolites. In this review, we evaluated both pre-synthesis and post-synthesis modification strategies with more focus on post-synthesis modification strategies. The role of various synthesis strategies on the intrinsic properties of hierarchical zeolites is discussed. The catalytic performance of hierarchical zeolites in important biomass reactions, such as catalytic pyrolysis of biomass feedstock and upgradation of bio-oil, has been summarized. The utilization of hierarchical zeolites tends to give a higher aromatic yield than conventional zeolites with microporosity solely. Full article
