ZnFe2O4 pour des applications en photocatalyse hétérogène dans le visible, ZnFe2O4 for heterogeneous photocatalysis applications in the visible

Aya Jezzini

Ce travail de thèse concerne la dépollution des eaux en utilisant des mélanges très enrichis en ferrite de zinc et activés par de la lumière visible. Nos solides ont été testés pour deux réactions : 1) l’oxydation et décomposition d’un antibiotique, l’amoxyciline ou AMX très utilisée en médecine…, Our work is devoted to the water depollution by photocatalysis with mixtures enriched in Zn ferrites and under visible light. It concerns 1) Amoxicilin (AMX), as one of the pharmaceutical polluting molecule that can be found in water and may have a toxic effect. 2) Bacterium Staphylococcus…

Design de composites verts pour la dépollution des terres agricoles : expérience et théorie, Design of green composite for the decontamination of agricultural land : experimental and theoretical

Khaled El Adraa

Des matériaux verts biodégradables à base de Montmorillonite et de cystéine ont été préparés dans le but de co-adsorber des cations de métaux lourds et des polluants émergeants en combinant l’expérience et la théorie (calculs DFT). Les analyses thermiques différentielles ont permis d’estimer le…, Layered silicates like smectites are important soil components. Many works have been devoted to functionalize these materials in order to increase their chelating properties which may help retain heavy metals. It is well known that Cd2+, Hg2+, Pb2+, Co2+ and Zn2+ forms stable complexes with sulfur-…

Control of the anisotropic shape of cobalt nanorods in the liquid phase: from experiment to theory… and back

Kahina Aït Atmane, Carine Michel, Jean-Yves Piquemal, Philippe Sautet, Patricia Beaunier, Marion Giraud, Mickaël Sicard, Sophie Nowak, Rémi Losno, G. Viau

The polyol process is one of the few methods allowing the preparation of metal nanoparticles in solution. Hexagonal close packed monocrystalline Co nanorods are easily obtained in basic 1,2-butanediol at 448 K after a few minutes using a Co(II) dicarboxylate precursor. By using a combined…

Selectivity in the gas-phase hydrogenation of 4-nitrobenzaldehyde over supported Au catalysts

Noémie Perret, Xiaodong Wang, Thomas Onfroy, Christophe Calers, Mark A Keane

The effects of Au particle size and support properties have been examined in the gas-phase hydrogenation of 4-nitrobenzaldehyde over Au/ZrO2, Au/TiO2 and Au/Al2O3. Gold particle size was varied using deposition-precipitation and impregnation syntheses. The catalysts have been characterised in terms…

Optimizing the immobilization of gold nanoparticles on functionalized silicon surfaces: amine- vs thiol-terminated silane

Maroua Ben Haddada, Juliette Blanchard, Sandra Casale, Jean-Marc Krafft, Anne Vallée, Christophe Méthivier, Souhir Boujday

Immobilization of gold nanoparticles on planar surfaces is of great interest to many scientific communities; chemists, physicists, biologists, and the various communities working at the interfaces between these disciplines. Controlling the immobilization step, especially nanoparticles dispersion…

Silk Polymers and Nanoparticles: A Powerful Combination for the Design of Versatile Biomaterials

Cristina Belda Marín, Vincent Fitzpatrick, David Kaplan, Jessem Landoulsi, Erwann Guénin, Christophe Egles

Silk fibroin (SF) is a natural protein largely used in the textile industry but also in biomedicine, catalysis, and other materials applications. SF is biocompatible, biodegradable, and possesses high tensile strength. Moreover, it is a versatile compound that can be formed into different materials…

Intermittent dynamics of bubble dissolution due to interfacial growth of fat crystals

Irma Liascukiene, Gabriel Amselem, Jessem Landoulsi, Deniz Gunes, Charles Baroud

Foams are inherently unstable objects, that age and disappear over time. The main cause of foam aging is Ostwald ripening: smaller air bubbles within the foam empty their gas content into larger ones. One strategy to counter Ostwald ripening consists in creating armored bubbles, where solid…

Au-Ru/TiO2 prepared by deposition-precipitation with urea: Relevant synthesis parameters to obtain bimetallic particles

Lina Calzada, Catherine Louis, Chang Wan Han, Volkan Ortalan, Rodolfo Zanella

Although Au and Ru are not miscible in the bulk, the paper focusses on the attempts to prepare bimetallic Au-Ru/TiO2 catalysts by deposition-precipitation with urea (co-DPU and sequential DPU, Au then Ru and vice versa). Gold was found already reduced after the preparations of co-DPU and Ru then Au…

Effect of ceria promotion on the catalytic performance of Ni/SBA-16 catalysts for CO 2 methanation

Chao Sun, Patricia Beaunier, Patrick da Costa

The presence of Ce inside the SBA-16 structure promoted the ratio of Ce 3+ and medium basic sites and thus favoured CH 4 formation.
