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…

Fluorescent core-shell nanoparticles and nanocapsules using comb-like macromolecular RAFT agents: synthesis and functionalization thereof

Chloé Grazon, Jutta Rieger, Patricia Beaunier, Rachel Méallet-Renault, Gilles Clavier

Fluorescent nanoparticles and nanocapsules (FNPs) were synthesized via a one-pot RAFT miniemulsion process copolymerizing BODIPY-methacrylate and styrene in water. Ultra-bright sub-100 nm core–shell nanoparticles could be obtained with BODIPY covalently linked in the core, and possessing various…

Identification and Distribution of Surface Ions in Low Coordination of CaO Powders with Photoluminescence Spectroscopy

Hugo Petitjean, Jean-Marc Krafft, Michel Che, Helene Lauron-Pernot, Guylene Costentin

Oxide ions in low coordination (O-LC(2-)) Play a major role in adsorption and catalysis properties of CaO powders. They also give specific photoluminescence features that could be used to characterize the distribution of these ions at the molecular level, but up to now, the photoluminescence of…

Should W Surface Density of WOx-ZrO2 Catalysts Be Calculated With Respect To the Specific Surface Area of the Sample or That of ZrO2 Only?

Cyril Thomas

On the basis of the critical analysis of the NOx-TPD data obtained on WOx-ZrO2 samples [Law, H. Y.; Blanchard, J.; Carrier, X.; Thomas, C. J. Phys. Chem. C 2010, 114, 9731], this work provides convincing arguments for the first time upon which calculation of W surface density should be done by…

Etude du front de minéralisation du tissu osseux et des modèles biomimétiques associés, Study of the mineralization front in bone tissue and in biomimetic models

Marc Robin

Les travaux réalisés ont pour but de répondre à deux questions : comment le collagène s'organise-t-il dans l'os mature ? Comment la phase minérale de l'os se forme-t-elle et quel est l'effet de son environnement sur sa formation ? Nous avons étudié d'un point de vue…, This work aims to understand: How is reached the plywood architecture in bone? How is bone apatite formed and what is the effect of the environment on apatite formation? Thus, histological bone thin sections were investigated focusing on the interface between the osteoid and mature bone tissues.…

Effect of postsynthesis preparation procedure on the state of copper in CuBEA zeolites and its catalytic properties in SCR of NO with NH3

Rafal Baran, Frederic Averseng, Dominik Wierzbicki, Karolina Chalupka, Jean-Marc Krafft, Teresa Grzybek, Stanislaw Dzwigaj

Copper-containing BEA zeolites, Cu2.0SiBEA and Cu2.0HAlBEA, with 2 wt % of Cu were prepared by a two-step postsynthesis method and a conventional wet impregnation, respectively. These zeolites were characterized by XRD, DR UV–vis, EPR, FTIR and TPR physicochemical techniques. The incorporation of…

Rh-Ni/SBA-15 prepared by two solvents method as stable catalysts for the dry reforming of methane at high pressure

M.N. Kaydouh, El Hassan N., Elzakhem H., Anne Davidson, Sandra Casale, Pascale Massiani

The effect of Rh addition on the catalytic performance of Ni/SBA-15 catalysts was studied in the dry reforming of methane. The SBA-15 silica support was synthesized in large quantities and the metals were deposited using the two solvents impregnation method. The properties of the calcined, reduced…
