Article
Full-text available
ITQ-13 is a medium-pore zeolite that can be prepared in all-silica form and as silicogermanate with Si/Ge ratios as low as 3. Usually synthesised in the presence of fluoride, ITQ-13 is among the very few systems containing fluoride anions in two distinct cage types, cube-like d4r units and [4·5 6 ] cages. Here, dispersion-corrected density function...
Article
The many studies that have been conducted on water adsorption on zeolites were carried out in “adsorption” mode, from adsorption isotherms or single‐point measurements, with the samples being first degassed at high temperature, and then exposed to water vapor at variable partial pressure. Here, we report Thermogravimetric Analysis (TGA) studies of...
Article
Two-dimensional 1H-31P heteronuclear correlation NMR of trimethylphosphine oxide (TMPO) adsorbed in zeolites, in tandem with DFT calculations, challenges previous one-dimensional 31P NMR assignments, enabling the unambiguous discrimination of Brønsted and...
Article
Composite agarose films were prepared with Eu(III) containing polyoxometalates, in particular the organic‐inorganic hybrid [Eu(W5O18)2(pic)4]13‐ (Hpic = 3‐hydroxypicolinic acid) and a Mo blue Eu(III) derivative. The latter compound shows interesting Eu(III) based photoluminescent properties, firstly described for a molybdenum blue compound. Imaging...
Article
The identification of acid and nonacid species at the external surface of zeolites remains a major challenge, in contrast with the much‐studied internal acid sites. Here, we show that the synthesis of zeolite ZSM‐5 samples with distinct particle sizes, combined with solid‐state NMR and computational studies of trimethylphosphine oxide (TMPO) adsorp...
