Catalytic behavior of nickel loaded on acid-activated and pillared clay in total gas-phase oxidation of ethanol

Nadjat Lahoues-Chakour, Siham Barama, Akila Barama, Brahim Djellouli, Cyril Domingos, Anne Davidson

Layered and acid-activated clays, used as catalytic support, were synthesized from natural Algerian montmorillonite. All supports were prepared by (1) pillaring with aquo/hydroxo/oxo Al clusters, in particular Al13 that contains only octahedral Al-species, (2) an acidic H2SO4 treatment, and (3)…

On the preparation of multifunctional conversion coatings of FePO 4 /LiFePO 4

S. Valverde-Pérez, R. Figueroa, X.R. Nóvoa, D.S. Ramírez-Rico, Vincent Vivier

This research aims to take advantage of the properRes of phosphate coaRngs to overcome the problems inherent in using LiFePO4 as a powder. LiFePO4 coaRngs have been prepared on iron sheets using cyclic voltammetry in an aqueous soluRon of H3PO4 and LiOH. The voltammograms evolved from the iniRal…

Investigating the DMPO-formate spin trapping method for the study of paper iron gall ink corrosion

Alice Gimat, Valeryia Kasneryk, Anne-Laurence Dupont, Sabrina Paris, Frederic Averseng, Jeanine Fournier, Pascale Massiani, Véronique Rouchon

Paper degradation by iron gall ink is a challenging issue for the conservation of ancient manuscripts. It is usually attributed to both FeII catalyzed oxidation and acid catalyzed hydrolysis of cellulose, yet the dominant degradation pathway remains an open question. In this work, electron spin…

Assessing carbon or tungstates coverage of ZrO2 nanoparticles supported on MWCNT via NOx-TPD

Patrick Kelleher, Gary Haller, Sandra Casale, Christophe Méthivier, Cyril Thomas

Multi-walled carbon nanotubes (MWCNT) promoted by oxides, that are far from trivial to characterize, have emerged as promising candidates in several fields such as biosensors and catalysis. In this study the coverage of ZrO2 nanoparticles supported on MWCNT, by carbonaceous deposits or tungstates…

Boronic species as promising inhibitors of the Staphylococcus aureus NorA efflux pump: Study of 6-substituted pyridine-3-boronic acid derivatives

Fanny Fontaine, Arnaud Héquet, Anne-Sophie Voisin-Chiret, Alexandre Bouillon, Aurélien Lesnard, Thierry Cresteil, Claude Jolivalt, Sylvain Rault

In response to the extensive use of antibiotics, bacteria have evolved numerous mechanisms of defense against antimicrobial agents. Among them, extrusion of the antimicrobial agents outside the bacterial cell through efflux pumps is a major cause of concern. At first limited to one or few…

Sulfur Deactivation of NOx Storage Catalysts: A Multiscale Modeling Approach.

Nikola Rankovic, Céline Chizallet, Andre Nicolle, David Berthout, Patrick da Costa

Lean NOx Trap (LNT) catalysts, a promising solution for reducing the noxious nitrogen oxide emissions from the lean burn and Diesel engines, are technologically limited by the presence of sulfur in the exhaust gas stream. Sulfur stemming from both fuels and lubricating oils is oxidized during the…

Effect of Cs impregnation on the properties of platinum in Pt/Na-BEA and Pt/Cs-BEA catalysts

Pascale Massiani, E.R. Silva, F.R. Ribeiro, M.F. Ribeiro, J.M. Silva

The presence of alkali cations in zeolite framework provides peculiar basic properties that influence the characteristics and reactivity of supported metal particles. Particularly, the addition of increasing amounts of cesium in Pt/Na-BEA and Pt/Cs-BEA catalysts, by CsOH impregnation, leads to…

NO2 disproportionation for the IR characterisation of basic zeolites

Olivier Marie, Nicolas Malicki, Catherine Pommier, Pascale Massiani, Ann Vos, Robert Schoonheydt, Paul Geerlings, Carlos Henriquese, Frédéric Thibault-Starzyk

NO2 disproportionation on alkaline zeolites is used to generate nitrosonium (NO+) and nitrate ions on the surface, and the infrared vibrations observed are very sensitive to the cation chemical hardness and to the basicity of zeolitic oxygen atoms.side pockets of acidic mordenite. We describe here…
