On the reactivity of NO/N2 mixtures with aluminum surfaces: a combined PM-IRRAS and QCM investigation

Aude Delebecque, Cyril Thomas, Claire-Marie Pradier, Christophe Methivier, Hervé Paoli, Martine Carré, Eric Coffre

Abstract. The interaction of NO, and the further reactivity of oxygen, with water-passivated aluminum surfaces are investigated for the first time by in situ Polarization Modulation Infrared Reflexion Absorption Spectroscopy (PM-IRRAS) coupled with Quartz Crystal Microbalance (QCM). Chemical and…

TiO2-supported Rh nanoparticles: From green catalyst preparation to application in arene hydrogenation in neat water

Claudie Hubert, Audrey Denicourt-Nowicki, Patricia Beaunier, Alain Roucoux

TiO2-supported Rh(0) nanoparticles were prepd. by an easy method under mild conditions in neat water. They proved to be highly active catalysts for arene hydrogenation in water with TOFs up to 33 333 h-1. [on SciFinder(R)]

Dispersion and hydrogenation activity of surfactant-stabilized Rh(0) nanoparticles prepared on different mesoporous supports

Maya Boutros, Guillaume Shirley, Thomas Onfroy, Franck Launay

Supported Rh(0) colloidal particles were prepared by the reduction of Rh(III) ions by sodium borohydride in the presence of N-N-dimethyl-N-cetyl-N-(2-hydroxyethyl) ammonium chloride (HEA16Cl), usually used as a stabilizing agent in solution. Tested supports were Na-Al-SBA-15, SBA-15 and CMK-3. In…

Formation of heteropolymolybdates during the preparation of Mo and NiMo HDS catalysts supported on SBA-15: Influence on the dispersion of the active phase and on the HDS activity

Alvaro Sampieri, Stephane Pronier, Sylvette Brunet, Xavier Carrier, Catherine Louis, Juliette Blanchard, Katia Fajerwerg, Michele Breysse

Mo and Ni-Mo sulfides in SBA-15 and Al-SBA-15 catalysts were prepd. by incipient wetness co-impregnation of molybdenum and nickel precursors (followed by thermal treatment under He at 823 K) and sulfidation under 10% H2S/H2 at 673 K. Only incipient wetness impregnation of Mo on pure silica SBA-15…

Incorporation of Nb(V) into BEA zeolite investigated by XRD, NMR, IR, DR UV-vis, and XPS

Stanislaw Dzwigaj, Yannick Millot, Christophe Methivier, Michel Che

Nb(x)SiBEA (x = 1.0, 1.5 Nb wt%) zeolites are prepared by a two-step postsynthesis method involving first the creation of vacant T-atom sites associated with silanol groups by dealumination of BEA zeolite by nitric acid solution and then by impregnation of the resulting SiBEA zeolite with the…

Stochastic Simulation and Single Events Kinetic Modeling: Application to Olefin Oligomerization

Javad Sharouzi, Denis Guillaume, Pierre Rouchon, Patrick da Costa

In order to handle a tractable network for complex reaction systems such as oligomerization, stochastic tools are applied to reduce the reaction mechanism. The particularity of this work is that quantitative single event kinetic modeling constants are used to generate a network which correctly…

Influence of the pretreatment conditions on the performances of CeO2-supported gold catalysts in the Catalytic Wet Air Oxidation of carboxylic acids

Ngoc D. Tran, Michèle Besson, Claude Descorme, Katia Fajerwerg, Catherine Louis

Two series of ceria-supported gold catalysts (1 and 4 wt.% Au) were prepared by deposition-precipitation with urea. Depending on the gold loading, the pretreatment of the Au/CeO2 catalysts (calcination in air vs. reduction in hydrogen) had a great influence on the oxidation state of gold, and in…

Selective Modification of the Acid-Base Properties of Ceria by Supported Au

Manuela C.I. Bezen, Cornelia Breitkopf, Nadia El Kolli, Jean-Marc Krafft, Catherine Louis, J.A. Lercher

Au supported on CeO2 prepared by deposition-precipitation with urea leads to a basic catalyst. Au acts in two ways as surface modifier. First, Au selectively interacts with Ce4+ cations by either blocking access to or reducing Ce4+ to Ce3+. Second, the resulting Au atoms (presumably as Au+ ions)…
