Insights into the influence of the Ag loading on Al2O3 in the H2-assisted C3H6-SCR of NOx

Tesnim Chaieb, Laurent Delannoy, Guylène Costentin, Catherine Louis, Sandra Casale, Ruth L. Chantry, Z.Y. Li, Cyril Thomas

The addition of H2 has been reported to promote drastically the selective catalytic reduction of NOx by hydrocarbons (HC-SCR). Yet, the influence of the Ag loading on the H2-promoted HC-SCR has been the subject of a very limited number of investigations. The H2-HC-SCR earlier studies reported…

The role of organic additives in the synthesis of mesoporous aluminas and Ni/mesoporous alumina catalysts

Faiza Bentaleb, Eric Marceau

Mesoporous aluminas can be prepd. using org. additives as porogens even if these are not surfactants, as is the case for glucose. It is shown here that porosity arises from glucose entrapped in the material pptd. at the beginning of the synthesis, and subsequently caramelized. After impregnation by…

Amphiphilic block copolymer nano-fibers via RAFT-mediated polymerization in aqueous dispersed system

Stephanie Boisse, Jutta Rieger, Khaled Belal, Aurelie Di-Cicco, Patricia Beaunier, Min-Hui Li, Bernadette Charleux

Self-assembled block copolymer nanofibers are attractive materials for multiple applications. We propose here a novel, very simple and straightforward method to prepare polymeric nanofibers at high solids contents directly in water. It is based on an aqueous emulsion polymerization process…

In Vitro Cytotoxicity and Transforming Potential of Industrial Carbon Dust (Fibers and Particles) in Syrian Hamster Embryo (SHE) Cells

C. Darne, F. Terzetti, C. Coulais, Jeanine Fournier, Y. Guichard, L. Gate, S. Binet

Carbon fibers have many applications, mainly in high-tech industries such as the aviation industry. Eleven carbon samples (fibers and particles) coming from an aeronautic group were tested for their cytotoxicity and carcinogenic potential using in vitro short-term assays in Syrian hamster embryo…

Structure of clean and hydrated alpha-Al2O3 (1(1)over-bar02) surfaces: implication on surface charge

Asma Tougerti, Christophe Methivier, Sylvain Cristol, Frederik Tielens, Michel Che, Xavier Carrier

Periodic DFT calculations coupled to a first-principle thermodynamic approach have allowed us to establish a surface phase diagram for the different terminations of the alpha-Al2O3 (1 (1) over bar 02) surface in various temperature and water pressure conditions. Theoretical results are compared…

Coordination chemistry approach for the end-to-end assembly of gold nanorods

P.R. Selvakannan, Eddy Dumas, Frédéric Dumur, Christine Péchoux, Patricia Beaunier, Arnaud Etcheberry, Francis Secheresse, Hynd Remita, Cédric Mayer

Gold nanorods synthesized by radiolysis were selectively end-functionalized by a fully conjugated thiol bearing a pendant terpyridine group; addition of ferrous ions led to the end-to-end 1D self-assembly of the nanorods. Similar results have been obtained when the preformed [(HStpy)Fe(tpySH)](2+)…

Heterogeneous catalyst preparation in ionic liquids: Titania supported gold nanoparticles

Camella Oumahi, Jean Lombard, Sandra Casale, Christophe Calers, Laurent Delannoy, Catherine Louis, Xavier Carrier

This work reports the use of ionic liquids (ILs) as solvent for the synthesis of Au/TiO2 heterogeneous catalysts. It is shown that the versatility of the physico-chemical properties of ILs makes them interesting solvents for a broad control of supported metal nanoparticles (NPs) size and for a fine…

Conception raisonnée de catalyseurs bifonctionnels : élaboration de catalyseurs Pt0/zéolithe-Alumine, Rational design of bifunctional catalysts : development of Pt0/zeolithe-alumina catalysts

Olfa Ben Moussa

Les catalyseurs bifonctionnels pour l’hydrocraquage nécessitent à la fois des sites acides de Brønsted et des sites métalliques. L’intimité entre sites acides et sites métalliques peut donc influer sur l’activité et la sélectivité de la réaction. Nous nous sommes proposés d’explorer l’effet de la…, Bifunctional hydrocracking catalysts require both Brønsted acid sites and metal sites. Hence, the intimacy between acid sites and metal sites can influence the activity and selectivity of the reaction. We intended to explore the effect of metal sites-acid sites distance on the conversion of n-…
