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…

A Study of Cobalt Speciation in Co/Al2O3 Catalysts Prepared from Solutions of Cobalt-Ethylenediamine Complexes

François Dumond, Eric Marceau, Michel Che

The thermal reduction of Co/Al2O3 catalysts prepared by impregnation of Co(II) nitrate generally leads to migration of cobalt ions into alumina with formation of cobalt aluminate. In order to prevent the latter, it is attempted to reduce cobalt by decomposition of supported precursor salts…

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…

Influence of the nature and environment of manganese in Mn-BEA zeolites on NO conversion in selective catalytic reduction with ammonia

Rafal Baran, L. Valentin, J.-M. Krafft, T. Grzybek, P. Glatzel, Stanislaw Dzwigaj

Manganese-containing BEA zeolites, MnxSiBEA (x = 1–4 wt %) and Mn(I.E.)AlBEA, were prepared by a two-step postsynthesis method and a conventional wet ion-exchange, respectively, and applied as catalysts in the selective catalytic reduction of NO with ammonia (NH3-SCR). The physicochemical analysis…

Time-resolved infrared spectroscopy in the study of photosynthetic systems.

Alberto Mezzetti, Winfried Leibl

Time-resolved (TR) infrared (IR) spectroscopy in the nanosecond to second timescale has been extensively used, in the last 30 years, in the study of photosynthetic systems. Interesting results have also been obtained at lower time resolution (minutes or even hours). In this review, we first…

Cristallisation de nanoparticules d'oxydes (MnO2, Co3O4, gamma-Fe2O3) dans les mésopores de silices

Anne Davidson, Vincent Dupuis, Regine Perzynski, Nissrine El Hassan, Marianne Imperor-Clerc, Dominique Bazin, Patricia Beaunier, Marie Dominique Appay

Du fait du grand nombre d'atomes exposés sur leur surface et de propriétés redox particulières, des nanoparticules d'oxydes de métaux de transition pourraient avantageusement remplacer les métaux nobles pour la gestion de problèmes environnementaux (élimination de CO à basse température,…

Structure–Activity Relationship in Manganese Perovskite Oxide Nanocrystals from Molten Salts for Efficient Oxygen Reduction Reaction Electrocatalysis

Francisco Gonell, Carlos M Sánchez-Sánchez, Vincent Vivier, Christophe Méthivier, Christel Laberty-Robert, David Portehault

We report a synthesis pathway in molten salts toward ligand-free nanoparticles of the layered perovskite La0.5Sr1.5MnO4 (l-LSMO) and of the pseudocubic perovskite La0.7Sr0.3MnO3 (pc-LSMO). These particles are readily implemented as oxygen reduction reaction (ORR) electrocatalysts in alkaline…
