Chiral Ammonium-Capped Rhodium(0) Nanocatalysts: Synthesis, Characterization, and Advances in Asymmetric Hydrogenation in Neat Water

Elodie Guyonnet Bil É, Elodie Cortelazzo-Polisini, Audrey Denicourt-Nowicki, Rita Sassine, Franck Launay, Alain Roucoux

Optically active amphiphilic compounds derived from N-methylephedrine, N-methylprolinol, or cinchona derivatives possessing bromide or chiral lactate counterions were efficiently used as protective agents for rhodium(0) nanoparticles. The full characterization of these surfactants and the obtained…

Effect of vanadium dispersion and of support properties on the catalytic activity of V-containing silicas

Marco Piumetti, Barbara Bonelli, Pascale Massiani, Stanislaw Dzwigaj, Ilenia Rossetti, Sandra Casale, Marco Armandi, Cyril Thomas, Edoardo Garrone

Two V-SBA-15 and V-MCF materials (containing about 2.5 wt.% vanadium) were prepared by direct synthesis and tested as catalysts in the decomposition of the most stable chlorinated-alkane, dichloromethane (a total oxidation reaction) and in the oxidative dehydrogenation (ODH) of propane (a partial…

Physico-chemical properties of FeAlBEA and FeSiBEA zeolites and their catalytic activity in the SCR of NO with ethanol or methane

Janusz Janas, Stanislaw Dzwigaj

FeAlBEA and FeSiBEA zeolites are prepared by a conventional ion exchange and a two-step postsynthesis method, respectively. Their physico-chemical properties are investigated by XRD, FTIR, and diffuse reflectance UV-vis. For FeAlBEA zeolite, framework tetrahedral Fe(III), extra-framework octahedral…

Controlled preparation of CoPdSiBEA zeolite catalysts for selective catalytic reduction of NO with methane and their characterisation by XRD, DR UV-vis, TPR, XPS

Ana Rodrigues, Patrick da Costa, C. Methivier, S. Dzwigaj

The Pd0.15SiBEA and CoxPd0.15SiBEA zeolites (where x= 1.0 and 3.0 wt.% Co) are prepared by a two-step postsynthesis method which allows to control the introduction of palladium and cobalt into zeolite and thus to obtain catalysts with specific bimetallic Pd and Co sites. The effect of Co content on…

Fatty Acid Monolayers on Randomly Nanostructured Inorganic Surfaces: Interplay of Wettability, Chemistry, and Topography

Mathieu Beauvais, Irma Liascukiene, Alain Jonas, Jessem Landoulsi

Understanding the wetting properties of chemically modified inorganic surfaces with random nanoscale topographies is of fundamental importance for diverse applications. This issue has hitherto continuously been the subject of considerable controversies. Herein, we report a thorough investigation of…

Polyoxotungstates-stabilized gold nanoparticles: how to transfer from an aqueous suspension to CH3CN ?, Nanoparticules d'or stabilisées par des polyoxotungstates : comment passer d'une suspension aqueuse à CH3CN ?

Jean-Baptiste Harlé, Élise Péruse, Jimika Hassanaly, Dalil Brouri, Anna Proust, Audrey Denicourt-Novicky, Alain Roucoux, Anne Gauvin-Bialecki, Richard Villanneau

The present study aims to evaluate available methods for preparing suspensions of gold nanoparticles stabilized by polyoxometalates (POMs@AuNPs) in CH3CN, a solvent commonly used in oxidation reactions. POMs@AuNPs are successfully synthesized in CH3CN using three different approaches: i) in situ…

Conversion of xylene over mordenites: an operando infrared spectroscopy study of the effect of Na+

Pascale Massiani, Olivier Marie, Frédéric Thibault-Starzyk

A series of progressively proton-exchanged sodium mordenite samples was studied by operando infrared spectroscopy during xylene conversion. This unique, powerful tool allowed us to characterize the species adsorbed to the surface during catalysis and to follow the evolution of the active sites as…
