Influence of the Ageing and Drying Steps of a CoMoP/γ‐Al2O3 Catalyst onto the Multi‐Scale Molybdenum Active Phase Organization

Candice Cottrez, Séverine Humbert, Anne‐sophie Gay, Elodie Devers, Frédéric de Geuser, Xavier Carrier, Alexandra Chaumonnot

To study the influence of ageing and drying steps onto the multiscale Mo active phase arrangement (i. e. MoS2 slabs and slab aggregates), a series of highly loaded CoMoP/γ-Al2O3 catalysts aged, unaged, dried or freeze-dried were prepared and tested in toluene hydrogenation. Electron Probe Micro…

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,…
