Hierarchical zeolites are a class of microporous catalysts and adsorbents that also contain mesopores, which allow for fast transport of bulky mols. and thereby enable improved performance in petrochem. and biomass processing. We used repetitive branching during 1-step hydrothermal crystal growth to synthesize a new hierarchical zeolite made of orthogonally connected microporous nanosheets. The nanosheets are 2 nm thick and contain a network of 0.5-nm micropores. The house-of-cards arrangement of the nanosheets creates a permanent network of 2- to 7-nm mesopores, which, along with the high external surface area and reduced micropore diffusion length, account for higher reaction rates for bulky mols. relative to those of other mesoporous and conventional MFI zeolites.
