129Xe-NMR of physisorbed xenon used as a probe for the study of microporous solids
Autor: Marie-Anne Springuel-Huet, Jacques Fraissard, J.-L. Bonardet
Publikováno v: Applied Magnetic Resonance. 8:427-456
129Xe-NMR of adsorbed xenon is of increasing interest for studying the physical properties of solids: cavity or channel dimensions; short-range crystallinity; nature of structural defects, polymer heterogeneity, etc. This review, which does not claim

A Comparative-Study of the Microporosity of the Ammonium and Cesium Salts of 12-Tungstophosphoric, 12-Molybdophosphoric, and 12-Tungstosilicic Acids by Xe129 NMR
Autor: J. L. Bonardet, G. B. Mcgarvey, John B. Moffat, J. Fraissard
Publikováno v: Journal of Catalysis. 151:147-154
The Xe 129 NMR method has been applied to the ammonium and cesium salts of 12-tungstophosphoric, 12-molybdophosphoric, and 12-tungstosilicic acids, as well as to the potassium salt of the first acid. The data obtained provide evidence for the presenc

Autor: R. I. Ben-Aim, J. L. Bonardet, A. M. Diamy, J. C. Legrand, J. Fraissard
Publikováno v: Journal of Materials Science. 25:4113-4119
Oxidation resistance of composite materials (SiC/SiC, C/SiC and C/C) which can be used to protect shuttles is studied in oxygen microwave-induced plasmas (MIP). These plasmas contain the same energetic species (electrons, ions, radicals, excited atom

129Xe-NMR study of coke distribution in dealuminated HY zeolites
Autor: J. L. Bonardet, M. C. Barrage, Jacques Fraissard
Publikováno v: Catalysis Letters. 5:143-154
Zeolites coking has been studied by129Xe-NMR technique. The distribution of the coke is heterogeneous on the supercage surface at low cokage level. When coking increases up to 10% the supercages are lined with coke and the residual internal volume co

NMR of Physisorbed 129Xe Used as a Probe to Investigate Molecular Sieves
Autor: J.-L. Bonardet, J. Fraissard, M.-A. Springuel-Huet, Antoine Gédéon
Publikováno v: Molecular Sieves ISBN: 9783540304579
Xenon is an inert gas with a very large electron environment that makes it sensitive to any interaction, even physical. In the case of 129Xe isotope (spin 1/2), the resulting electronic perturbation is directly transmitted to the nucleus and, therefo

Use of 1H NMR imaging to study the diffusion and co-diffusion of gaseous hydrocarbons in HZSM-5 catalysts
Autor: P. N'Gokoli-Kekele, Jean-Marie Dereppe, J. Fraissard, J.-L. Bonardet, M.-A. Springuel-Huet
Publisher Summary This chapter presents 1 H nuclear magnetic resonance (NMR) to study the diffusion of pure hydrocarbons during their adsorption in or desorption from a fixed bed of zeolite crystallites. This This technique is used to visualize the p
