About this collection
The synthesis and application of zeolite catalysts in various heterogeneous catalytic reactions has become a hot research topic because of their well-defined micropores and tunable active centers. Owing to their excellent catalytic performances, environmental-friendly properties and high thermal and hydrothermal stabilities, zeolites have gained broad popularity and been widely applied to various industrially important catalytic processes.
This themed collection, Guest Edited by Anmin Zheng (Wuhan Institute of Physics and Mathematics, China), Shutao Xu (Dalian Institute of Chemical Physics, China) and Kinga Góra-Marek (National Science Centre, Poland) aims to highlight the recent progress in zeolite catalysis, including the zeolite synthesis, in situ characterization, adsorption/diffusion, reaction mechanism, as well as the practical industrial applications. These reviews are of great significance for comprehensively understanding the origin and catalytic nature of zeolites, and should strongly promote the further rapid development of zeolite catalysis field. This collection showcases research across both heterogeneous catalysis and surface chemistry and brings systemic understanding of how to establish the structure-activity/selectivity relationships of zeolite catalysts and to reveal the reaction mechanisms at the molecular/atomic level.
