Elaboration, activity and stability of silica-based nitroaromatic sensors

D. Mercier, Franck Pereira, Christophe Méthivier, Pierre Montméat, Lionel Hairault, Claire-Marie Pradier

Functionalized silica-based thin films, modified with hydrophobic groups, were synthesized and used as sensors for nitroaromatic compound (NAC) specific detection. Their performance and behavior, in terms of stability, ageing and regeneration, have been fully characterized by combining chemical…

Calibrated Co3O4 nanoparticles patterned in SBA-15 3 silicas: Accessibility and activity for CO oxidation

Irène Lopes, Anne Davidson, Cyril Thomas

The catalytic performances in CO oxidation of Co3 O4 nanoparticles patterned in the porosity of SBA-15 silicas are investigated. 10 Accessibility limitations of the reactants to the catalytic sites are clearly revealed,when the Co3O4 nanoparticles are embedded in the 11 SBA-15 pores.Despite these…

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…

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…

High activity of mononuclear copper present in the framework of CuSiBEA zeolites in the selective catalytic reduction of NO with NH3

Rafal Baran, Teresa Grzybek, Thomas Onfroy, Stanislaw Dzwigaj

CuxSiBEA zeolites (with x = 1–7.5 Cu wt %) prepared by a two-step postsynthesis method which consists in the first step of dealumination of parent BEA zeolite to obtain aluminum-free SiBEA support and then in the second step, of contacting the obtained material with an aqueous solution of copper…

Characterizations and performances of Ni/diatomite catalysts for dry reforming of methane

Karam Jabbour, Nissrine El Hassan, Anne Davidson, Pascale Massiani, Sandra Casale

Monometallic 5 wt% Ni containing catalysts were prepared by a two-solvent (cyclohexane/water) deposition method using cheap and widely available natural diatomites (Ni/AW2 and Ni/MN3) as supports. The fresh samples were characterized by SEM, EDX microanalysis, N2 adsorption–desorption isotherms,…

Superior Stability of Au/SiO 2 Compared to Au/TiO 2 Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Herrick Schaink, Ad van Der Eerden, Jan Willem de Rijk, Tiago A. G. Silva, Dipanjan Banerjee, Johannes D. Meeldijk, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Supported gold nanoparticles are highly selective catalysts for a range of both liquid-phase and gas-phase hydrogenation reactions. However, little is known about their stability during gas-phase catalysis and the influence of the support thereon. We report on the activity, selectivity, and…
