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-…

New ammonium surfactant-stabilized rhodium(0) colloidal suspensions: influence of novel counter-anions on physico-chemical and catalytic properties.

Elodie Bile Guyonnet, Rita Sassine, Audrey Denicourt-Nowicki, Franck Launay, Alain Roucoux

Novel anionic species, such as hydrogen carbonate (HCO(3)(−)), fluoride (F(−)), triflate (CF(3)SO(3)(−)), tetrafluoroborate (BF(4)(−)) and chloride (Cl(−)) were investigated as new partners of water soluble N,N-dimethyl-N-cetyl-N-(2-hydroxyethyl) ammonium salts, used as a protective agent of…

Electron Transfer at the Metal Oxide/Electrolyte Interface: A Simple Methodology for Quantitative Kinetics Evaluation

Iban Azcarate, Cyrille Costentin, Christophe Méthivier, Christel Laberty-Robert, Alexis Grimaud

While quantitative models exist for measuring rate constants for electron exchange at the surface of semiconductors to or from redox couples in solution, their use is very limited for studying transition metal oxide electrodes. Taking advantage of the possibility of tuning the doping level of WO 3…

Preparation of Pt°/MCM-41: effect of drying on MCM-41 structure and Pt° dispersion

Baichun Zhu, Franck Letellier, Juliette Blanchard, Katia Fajerwerg, Catherine Louis, Denis Guillaume, Denis Uzio, Miehèle Breysse

Pt°/MCM-41 catalysts were prepared by electrostatic adsorption of Pt(NH3)42+ at pH=8, followed by calcination under O2 and reduction. This procedure allows to prepare highly dispersed Pt° nanoparticles (D>76%), but has the drawback to modify significantly the structure of the ordered mesoporous…
