129Xe NMR Study of the Framework Flexibility of the Porous Hybrid MIL-53(Al)
Marie-Anne Springuel-Huet,Andrei Nossov,Ziad Adem,Flavien Guenneau,Christophe Volkringer,Thierry Loiseau,Gérard Férey,Antoine Gédéon +7 more
TL;DR: The metal-organic framework MIL-53 exhibits a structural transition between two possible porous structures, so-called large- pore (lp) and narrow-pore (np) forms, depending on the temperature or when guest molecules are adsorbed, which is studied to quantify the rate of the structural transformation.

Specific Surface Area Determination for Microporous/Mesoporous Materials: The Case of Mesoporous FAU-Y Zeolites
Anne Galarneau,Dirk Mehlhorn,Flavien Guenneau,Benoit Coasne,François Villemot,Delphine Minoux,Cindy Aquino,Jean-Pierre Dath +7 more
TL;DR: A methodology for determining the micropore, mesopore, and external surface areas of hierarchical microporous/mesoporous materials from N2 adsorption isotherms at 77 K allows accurate characterization of the surface areas in FAU-Y zeolites.
Probing Interconnectivity in Hierarchical Microporous/Mesoporous Materials using Adsorption and Nuclear Magnetic Resonance Diffusion
Anne Galarneau,Flavien Guenneau,Antoine Gédéon,Diaa Mereib,Jeremy Rodriguez,François Fajula,Benoit Coasne,Benoit Coasne +7 more
TL;DR: In this paper, it was shown that adsorption at a given pressure can be described as a simple linear combination of the adsorbed amounts taken at the same pressure for the pure microporous (zeolite FAU-Y) and mesoporous (Al-MCM-41) solids.
Continuous flow hyperpolarized 129Xe-MAS NMR studies of microporous materials
Andrei Nossov,Flavien Guenneau,Marie-Anne Springuel-Huet,Elias Haddad,Valérie Montouillout,Benno Knott,Frank Engelke,Christian Fernandez,Antoine Gédéon +8 more
TL;DR: In this article, a magic angle spinning (MAS) NMR probe has been developed to allow in situ measurements of NMR spectra for working catalysts and porous materials under MAS and continuous flow conditions.

The first direct probing of porosity on supported mesoporous silica thin films through hyperpolarised 129Xe NMR
Andrei Nossov,Elias Haddad,Flavien Guenneau,Claude Mignon,Antoine Gédéon,David Grosso,Florence Babonneau,Christian Bonhomme,Clément Sanchez +8 more
TL;DR: In this article, the continuous flow hyperpolarized (HP) 129Xe NMR technique has been used for the first time on mesoporous silica thin films and demonstrates the possibility of recording information about the porosity of a small quantity of materials and the high sensitivity of the NMR response to pore size and pore functionality.
