Preparation of Hierarchical ZSM-5 Sheets with Diverse Quaternary Ammonium Hydroxides as Etching Agents

cations. To the best of our knowledge, this work demonstrates for the first time that the synergistic effect of framework aluminum enables weakly templating TBAOH to successfully form uniform sheets, a result not achievable with pure-silica zeolites. These findings highlight the critical interplay between etchant choice and zeolite composition and significantly expand the toolbox for the precise microstructural tailoring of zeolites.
