Vers une meilleure compréhension de la réduction sélective des oxydes d'azote par les hydrocarbures sur les catalyseurs à base d'argent et d'or supportés sur alumine, Towards a further understanding of the selective catalytic reduction of nitrogen oxides by propene on alumina supported silver and gold catalysts

Tesnim Chaieb

Ces travaux de thèse ont porté sur l'étude approfondie de catalyseurs à base d'argent et d'or dans la réduction catalytique sélective des NOx par C3H6. Pour le système Ag/Al2O3, nous avons réussi à fournir une explication rationnelle de l'origine de l'existence d'un…, This work provides further insights into C3H6-SCR on alumina supported silver and gold catalysts. The origin of the optimum loading of 2 wt% of Ag on Al2O3 in the C3H6-SCR of NOx was elucidated with the help of an original characterization method (NOx-TPD). The optimum loading was attributed to the…

Influence of Coadsorbed Water and Alcohol Molecules on Isopropyl Alcohol Dehydration on γ-Alumina: Multiscale Modeling of Experimental Kinetic Profiles

Kim Larmier, Andre Nicolle, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Successfully modeling the behavior of catalytic systems at different scales is a matter of importance not only for a fundamental understanding but also for a more rational design of catalysts and a more precise definition of the kinetic laws used as inputs in chemical engineering. We have developed…

One-Pot Radiolytic Synthesis of Gold Nanorods and Their Optical Properties

Wafa Abidi, P. R. Selvakannan, Yanick Guillet, Isabelle Lampre, Patricia Beaunier, Brigitte Pansu, Bruno Palpant, Hynd Remita

A novel one-pot synthesis method to prepare gold nanorods of different aspect ratios using radiolysis is presented. The gold nanorods are synthesized by radiolytic reduction of Au-III complexes in a micellar solution formed by a mixture of cationic surfactants (cetyltrimethylammonium bromide and…

Improvements in photostability and sensing properties of EuVO₄ nanoparticles by microwave-assisted sol–gel route for detection of H₂ O₂ vapors

Chrystel Ambard, Natacha Duée, Franck Pereira, David Portehault, Christophe Méthivier, Claire-Marie Pradier, Clément Sanchez

The inorganic thin-film fluorescence probe, with the advantages of long life span and high sensitivity, has attracted much attention in explosive detection. The poor ultraviolet absorption and lack of an aromatic ring make peroxide-based explosives very hard to detect. As the signature compound of…

Cysteine-montmorillonite composites for heavy metal cation complexation: A combined experimental and theoretical study

Khaled El Adraa, Thomas Georgelin, Jean-François Lambert, Farouk Jaber, Frederik Tielens, Maguy Jaber

Green composites based on montmorillonite (Mt) and cysteine, were prepared for heavy metal removal. A comparison between the adsorption properties of the resulting hybrid inorganic-organic materials and the pure montmorillonite was carried out for the following heavy metal cations Cd2+, Hg2+, Pb2…

Structure and Surface Study of Hydroxyapatite-Based Materials: Experimental and Computational Approaches

Guylène Costentin, Christophe Drouet, Fabrice Salles, Stéphanie Sarda

In addition to designing catalytic materials ever more active and selective, the emergence of new classes of greener catalysts remains very challenging. The apatite family system with hydroxyapatite (HA) structure appears as a good candidate for catalysis due to its eco-compatibility properties,…
