TL;DR: It is demonstrated that hydronium ions confined in the nanopores of zeolite HBEA catalyse aqueous phase dehydration of cyclohexanol at a rate significantly higher than hydronsium ions in water.

TL;DR: The higher charge density that accompanies an increasing concentration of hydronium ions leads to an increase in the activity coefficients of the adsorbed substrates, thus, weakening the interactions between the organic part of the molecules and the zeolite and favoring the interactions with polar groups.

TL;DR: In this paper, the intramolecular dehydration of cyclohexanol on H-MFI zeolites in water has been used to quantitatively show an enhancement of the reaction rate by the presence of high ionic strength.

TL;DR: In this article, the authors explored strategies to understand and mitigate the corrosive interactions of zeolites in aqueous phase under reaction conditions using zeolite BEA as an example.

TL;DR: It is shown that hydronium ion catalysis, exemplified by intramolecular dehydration of cyclohexanol, is markedly influenced by steric constraints, yielding turnover rates that increase by up to two orders of magnitude in tight confines relative to an aqueous solution of a Brønsted acid.
