TL;DR: In this article, the modifications of the state of aluminium when introducing protons into zeolite-β have been investigated by combining several analytical techniques, and it was concluded that the octahedrally coordinated and NMR invisible aluminium must be regarded as inherent parts of the framework of the Zeolite and their formation is explained by a distortion of aluminic sites caused by the high electron affinity of the proton.

TL;DR: In this article, five samples of zeolite omega have been synthesized under various experimental conditions in order to produce crystals exhibiting different chemical compositions and morphologies 29Si and 27Al MAS nmr spectroscopy have been used to determine the Al content of the framework and the Si-Al distributions over the two nonequivalent crystallographic sites.

TL;DR: In this article, the authors studied the crystallization kinetics of zeolites of structure TON synthesized in the presence of diethanolamine, triethylenetetramine, or methanol.

TL;DR: In this paper, synthetic faujasite, mazzite, and offretite have been dealuminated with ammonium hexafluorosilicate and their catalytic activity has been evaluated using isooctane cracking as test reaction.

TL;DR: In this article, the authors used NMR spectroscopy, X-ray diffraction, porosity measurements, chemical analysis and infrared spectroscopic analysis to study the changes in properties of zeolite Ω which occurred upon thermal activation.
