Summary:This study presents NH4F salt inclusion approach to creating additional mesopores within microporous zeolite Y. Etching with NH4F salts embedded in the supercages perfomrs the localized dissolution within the zeolite crystals to effectively create additional interconnected mesopores without deteriorating crystallinity. Our work provides a novel idea for tailoring pore architecture to design desirable porous materials. Creation of additional mesopores within zeolite Y through etching with embedded NH4F salts. [Display omitted] •A new approach to creating additional mesopores in microporous zeolite using NH4F salt as an etchant was proposed.•Etching with embedded NH4F salts in the cavities of zeolite Y performs the preferential dissolution in the intracrystalline region of the zeolite to create additional interconnected mesopores.•Additional mesoporosity was developed without formations of cracks or holes onto the crystals and the loss of crystallinity.
