Heterogeneous Partial (amm) Oxidation and Oxidative Dehydrogenation Catalysis on Mixed Metal Oxides

Jacques C. Védrine

This paper presents an overview of heterogeneous partial (amm)oxidation and oxidative dehydrogenation (ODH) of hydrocarbons. The review has been voluntarily restricted to metal oxide-type catalysts, as the partial oxidation field is very broad and the number of catalysts is quite high. The main…

Improvement of the Catalytic Performances of SBA‐15 in the Formylation of Aniline upon the Introduction of Template‐Free Nano‐Faujasite in Its Synthesis Gel

Karima Baghdad, Mohammed Abdelkrim Hasnaoui, Franck Launay

Faujasite nanoparticles with average size of 10–40 nm were obtained without any organic structure directing agents (Green synthesis), then used as precursors for the synthesis of NaY/SBA-15 composites. Two types of composites were obtained with meso/micro porosity (C1 and C2).The inorganic salt,…

Confinement effect of Nickel in mesoporous silica-based catalysts for syngas production by reforming of methane with CO2, Effet de confinement du nickel dans des catalyseurs à base de silice mésoporeuse pour la production de gaz de synthèse par reformage du méthane avec le CO2

Marie-Nour Kaydouh

Although economically and environmentally advantageous, the methane dry reforming process using supported nickel based catalysts still faces problems of active phase (a transition metal) sintering and of carbon deposition, which result in catalytic activity loss. This thesis is focused on the study…, Malgré ses avantages économiques et environnementaux, le procédé de reformage à sec du méthane sur des catalyseurs au nickel supporté se heurte encore à des problèmes de frittage de la phase active (un métal de transition) et de dépôt de carbone, ce qui entraîne une diminution de l'activité…

Amphiphilic Polyoxometalates for the Controlled Synthesis of Hybrid Polystyrene Particles with Surface Reactivity

Jennifer Lesage de la haye, Jean-Michel Guigner, Eric Marceau, Laurent Ruhlmann, Bernold Hasenknopf, Emmanuel Lacôte, Jutta Rieger

Amphiphilic organo-polyoxometalates (POMs) used in the radical emulsion polymerization of styrene allowed the preparation in aqueous medium of stable 50-100 nm polystyrene-POM composite latexes. Thanks to the presence of a trithiocarbonate group in the POM amphiphile, POMs could be covalently…

Ola El Samrout

This PhD thesis aims to deeply study the polymerization of Gly monomers on amorphous silica to better understand its reaction mechanism, kinetics, and parameters related to the nature of the condensation product obtained under different environmental conditions. In the first part, the behavior of…, Cette thèse vise à étudier en profondeur la polymérisation des monomères Gly sur de la silice amorphe afin de mieux comprendre son mécanisme réactionnel, sa cinétique et les paramètres liés à la nature du produit de condensation obtenu dans différentes conditions environnementales.

Halide-free CO 2 cycloaddition onto styrene oxide catalysed by first row transition-metal derivatives of polyoxotungstates

Jingjing Ren, Franck Launay, Richard Villanneau, Anna Proust

Quaternary ammonium salts of metal derivatives of polyoxometalates [XW11O39M(H2O)]n- (X = P, Si; M = Cr, Mn, Co, Ni, Zn) were successfully tested instead of quaternary ammonium halides as catalysts in the cycloaddition of CO2 to styrene oxide. Remarkably, they gave very satisfactory yields of…

Molten Salts‐Driven Discovery of a Polar Mixed‐Anion 3D framework at the nanoscale: Zn4Si2O7Cl2, Charge Transport and Photoelectrocatalytic Water Splitting

Ram Kumar, Yang Song, Anissa Ghoridi, Philippe Boullay, Gwenaelle Rousse, Christel Gervais, Cristina Coelho Diogo, Houria Kabbour, Capucine Sassoye, Patricia Beaunier, Victor Castaing, Bruno Viana, Maria Luisa Ruiz Gonzalez, José Gonzalez Calbet, Christel Laberty-Robert, David Portehault

Mixed-anion compounds widen the chemical space of attainable materials compared to single anionic compounds, but the exploration of their structural diversity is limited by common synthetic paths. Especially, oxychlorides rely mainly on layered structures, which suffer from low stability during…

Hydrodeoxygenation of Furfural over Unsupported, SiO 2 ‐supported or Metal‐promoted Mo Carbides: Tunning the Selectivity between 2‐Methylfuran and C 10 Furoins Diesel Precursors

Letícia Sosa, Priscilla de Souza, Raphaela Rafael, Robert Wojcieszak, E. Marceau, Sébastien Paul, Valérie Briois, Fabio Noronha, Fabio Toniolo

Abstract The hydrodeoxygenation of furfural (FF) over Mo carbides in liquid phase at 200 °C, 30 bar of H 2 for 4 h in 2‐butanol was investigated. Unsupported and SiO 2 ‐supported Mo carbide with different crystallographic phases (β‐Mo 2 C/SiO 2 and α‐MoC/SiO 2 ), and in the presence of Cu and Ni as…
