TLDR
In this article, it was shown that the presence of the bulkier potassium cations causes a significant diminution of the accessible Bronsted acid sites in the large cages and of the catalytic activity.About:

Probing zeolites by vibrational spectroscopies
Silvia Bordiga,Carlo Lamberti,Carlo Lamberti,Francesca Bonino,Arnaud Travert,Frédéric Thibault-Starzyk +5 more
TL;DR: This review addresses the most relevant aspects of vibrational spectroscopies applied to zeolites and zeotype materials and describes the methods needed to precisely determine the IR absorption coefficients, making IR a quantitative technique.

Stability of Zeolites in Hot Liquid Water
Ryan M. Ravenelle,Florian Schüβler,Andrew D. D’Amico,Nadiya Danilina,Jeroen A. van Bokhoven,Johannes A. Lercher,Christopher W. Jones,Carsten Sievers +7 more
TL;DR: The main degradation mechanism is suggested to be hydrolysis of the siloxane bonds (Si−O−Si) as opposed to dealumination, which dominates under steaming conditions as discussed by the authors.
Journal ArticleDOI
Solid-state nuclear magnetic resonance investigations of the nature, property, and activity of acid sites on solid catalysts.
TL;DR: High-temperature and flow techniques of in situ solid-state NMR spectroscopy allow a deeper insight into the mechanisms of heterogeneously catalyzed reactions and open the way for studying the activity of acidic surface sites.
Journal ArticleDOI
Gas phase catalysis by zeolites
TL;DR: An overview of today's use of zeolites and related microporous materials as catalysts within the fields of refining, petrochemistry and commodity chemicals can be found in this paper.

Synthesis of new silica-rich cubic and hexagonal faujasites using crown-etherbased supramolecules as templates
TL;DR: In this article, two pure and well-crystallized faujasite-type zeolites were synthesized with a framework Si/Al ratio approaching 5: (1) the cubic phase with 15 crown-5, and (2) the hexagonal phase with 18 crown-6.
