Elaboration de catalyseurs hétérogènes en milieu liquide ionique : nanoparticules métalliques (Au et Au-Pd) supportées sur dioxyde de titane, Heterogeneous catalysts preparation in ionic liquid media : titania-supported metallic nanoparticles (Au and Au-Pd)

Camella Oumahi

Ces travaux portent sur l'élaboration de catalyseurs hétérogènes en milieu liquide ionique (LI). Ces sels liquides à température ambiante permettent d'ajuster les propriétés du solvant suivant la composition chimique du LI mis en jeu (sels d'imidazolium ou Deep Eutectic Solvent à…, This work deals with the elaboration of heterogeneous catalysts in ionic liquids (ILs). These salts, liquid at room temperature, were chosen because they permit to adjust the solvent properties depending on their chemical composition (imidazolium salts or Deep Eutectic Solvent based on choline…

Structural studies of adsorbed protein (betalactoglobulin) on natural clay (montmorillonite)

Ali Assifaoui, Lucie Huault, Cyrielle Maissiat, Chloé Roullier-Gall, Philippe Jeandet, Jerôme Hirschinger, Jesus Raya, Maguy Jaber, Jean-François Lambert, Philippe Cayot, Régis Gougeon, Camille Loupiac

In this work, the adsorption of a small globular protein (betalactoglobulin, BLG), on a natural montmorillonite clay (Mt) was investigated in acidic buffer (pH = 3). The combination of different characterization techniques such as zetametry, X-ray diffraction, transmission electronic microscopy,…

Nouvelles biocathodes graphite/nitrure de carbone amorphe/laccase pour la réduction de l'oxygène par transfert électronique direct

Achraft Blout, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Les enzymes constituent une alternative intéressante aux catalyseurs métalliques car elles possèdent une meilleure sélectivité et des performances catalytiques souvent plus élevées. Elles peuvent être utilisées dans différents types de dispositifs électrochimiques comme les piles à combustible1.…

Using planktonic microorganisms to supply the unpurified multi-copper oxidases laccase and copper efflux oxidases at a biofuel cell cathode

Sabine Sane, Katrin Richter, Stefanie Rubenwolf, Nina Joan Matschke, Claude Jolival, Catherine Madzak, Roland Zengerle, Johannes Gescher, Sven Kerzenmacher

The feasibility to apply crude culture supernatants that contain the multicopper oxidases laccase or copper efflux oxidase (CueO) as oxygen reducing catalysts in a biofuel cell cathode is shown. As enzyme-secreting recombinant planktonic microorganisms, the yeast Yarrowia lipolytica and the…

Physical techniques and catalyst preparation: Determining the interactions of transition-metal complexes with oxide surfaces

Xavier Carrier, Eric Marceau, Michel Che

This contribution presents the molecular approach used to investigate the different preparation steps of important catalytic systems, based on Mo, Ni, and Co. The first preparation step consists of impregnating oxide supports by aqueous solutions of transition-metal complexes (TMCs), called…

The Acidity of Zeolites: Concepts, Measurements and Relation to Catalysis: A Review on Experimental and Theoretical Methods for the Study of Zeolite Acidity

E.G. Derouane, Jacques C. Vedrine, Ramos R. Pinto, P.M. Borges, L. Costa, M. A. N. D. A. Lemos, F. Lemos, Ramôa Ribeiro

In this article, we considered all aspects of acidity (nature of acid sites, strength, density, etc.) in solid catalysts and in zeolites in particular. After reminding the definition of acidity in liquid and solid acids, we emphasized acidity characterization by the most used physical techniques,…
