Emerging applications of zeolites in catalysis, separation and host-guest assembly

Zeolites are a family of microporous crystalline materials, which, since the 1940s, have had an indispensable role in the chemical industry as catalysts, adsorbents and ion exchangers. Advances in synthetic methodologies and characterization techniques have enabled the fabrication of new zeolitic materials, with emerging applications in diverse areas. By tuning their porous architectures, framework compositions and crystal morphologies, coupled with the incorporation of exotic active species, zeolites and zeolite-based materials have exhibited unprecedentedly high performance in many challenging processes. In this Review, we focus on the high-efficiency catalytic production of industrially important hydrocarbons and oxygenates using non-petrochemical feedstocks, energy-efficient separations of hydrocarbon mixtures that are difficult using conventional methods and materials, and host-guest assemblies that exhibit physical properties unprecedented to either the zeolite hosts or free guest species. Finally, we provide our perspectives on future directions for the development of zeolitic materials to meet the ever-growing demands from diverse fields. New zeolitic materials have shown high performance in emerging applications across diverse areas. This Review focuses on the advances in zeolite applications, including the catalytic production of hydrocarbons and oxygenates from non-petrochemical feedstocks, the efficient separation of hydrocarbon mixtures that are otherwise challenging, and host-guest assemblies with unprecedented physical properties.
