TL;DR: It is shown that appropriately designed bifunctional surfactants can direct the formation of zeolite structures on the mesoporous and microporous length scales simultaneously and thus yield MFI (ZSM-5, one of the most important catalysts in the petrochemical industry) zeolites that are only 2 nm thick, which corresponds to the b-axis dimension of a single MFI unit cell.

TL;DR: A series of mesoporous molecular sieves are synthesized that possess crystalline microporous walls with zeolitelike frameworks, extending the application of zeolites to the mesoporus range of 2 to 50 nanometers.

TL;DR: The present approach using a zeolite structure-directing functional group contained in a surfactant would be suitable for the synthesis of other related nanomorphous zeolites in the future.

TL;DR: In this paper, a review of recent advances in synthesis routes to hierarchically nanoporous zeolites are reviewed with their catalytic contributions, focusing on the recently developed synthesis method which uses surfactants that are functionalized with a zeolite-structure-directing group.

TL;DR: This material has a Hammett acidity function H0 ≤ -14.5 and is thus identified as a superacid, providing the first evidence for superacidity in MOFs, attributed to the presence of zirconium-bound sulfate groups structurally characterized using single-crystal X-ray diffraction analysis.
