Condensed Matter Chemistry in Catalysis by Zeolites

This work is devoted to condensed matter chemistry in gas-phase catalytic reactions over zeolite catalysts, which mainly involve in the processes of (i) adsorption of gaseous reactants into zeolite micropores, (ii) conversion of the reactants on catalytic sites in zeolites, and ( iii) desorption of products in zeolites. In the above processes, both fast adsorption in zeolite micropores and rapid desorption from zeolites can significantly improve the reaction rate. To realize these purposes, it has been developed new strategies for rational synthesis of zeolites including preparation of zeolite nanocrystals, introduction of mesopores into zeolite crystals, preparation of zeolite nanosheets, and adjusting wettability of zeolite crystals, which have been simply concluded. Furthermore, the catalytically active sites including single atoms and metal nanoparticles can be introduced into zeolite frameworks or zeolite crystals, which can combine both the advantages of high stability and excellent shape selectivity for zeolites and the advantages of high activity and anti-deactivation for metal species together, offering a good opportunity to design and preparation of new highly efficient zeolite-based catalysts in the future. Finally, it is suggested perspectives such as rational synthesis of zeolite catalysts by theoretical simulations from the energy comparison, preparation of highly efficient catalysts by incorporating catalytically active sites in zeolite framework from the requirements of catalytic reactions, and green synthesis of zeolites for reduction of harmful gases, polluted water, and solid wastes in industrial processes.
