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…

Electrical surface properties of nanoporous alumina membranes: influence of nanochannels’ curvature, roughness and composition studied via electrokinetic experiments

Ali Vakilinejad, Emmanuelle Dubois, Laurent Michot, Marie Jardat, Didier Lairez, Serge Durand-Vidal, Clément Guibert, Nicolas Jouault

Among classical nanoporous oxide membranes, anodic aluminum oxide (AAO) membranes, made of non-connected, parallel and ordered nanochannels, are very interesting nanoporous model systems widely used for multiple applications. Since most of these applications involve local phenomena at the…

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…

Conception de systèmes catalytiques hétérogènes chimioenzymatiques pour l'époxydation, Conception of heterogeneous chemioenzymatic catalysts for epoxydation

Noémie Balistreri

L'objectif de ce travail est de développer un système catalytique hétérogène pour l'époxydation en utilisant directement O2 de l'air plutôt que H2O2 commercial. La stratégie adoptée a été de coupler la production in situ de H2O2, catalysée par la glucose oxydase (GOx), avec un…, The objective of this work was to develop an heterogeneous catalyst system supplied by dioxygen, rather than commercial H2O2, in order to carry out epoxidation reactions. Our strategy was to couple the in situ production of H2O2, catalyzed by glucose oxidase (GOx), with a Ti-based catalyst. The…

Gold surface nanostructuring for separation and sensing of biomolecules, Nanostructuration des surfaces d'or pour la séparation et la détection de biomolécules

Erin Bedford

Detecting biomolecules in physiological environments is critical to health care and environmental monitoring. In this work, we study and use gold surfaces for biomolecule detection while incorporating nanoscale components—specifically, self-assembled monolayers (SAMs) of alkanethiols and gold…, La détection de molécules biologiques dans les environnements physiologiques est essentielle aux soins de santé et la surveillance de l'environnement. Dans ces travaux de thèse, nous étudions et utilisons des surfaces d'or pour la détection de biomolécules, avec l'inclusion de…
