Silica-Supported Au-Ag Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Christophe Calers, Jean-Jacques Gallet, Fabrice Bournel, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Gold and silver are miscible over the entire composition range, and form an attractive combination for fundamental studies on bimetallic catalysts. Au–Ag catalysts have shown synergistic effects for different oxidation and liquid-phase hydrogenation reactions, but have rarely been studied for gas…

Au-Ru/TiO2 prepared by deposition-precipitation with urea: Relevant synthesis parameters to obtain bimetallic particles

Lina Calzada, Catherine Louis, Chang Wan Han, Volkan Ortalan, Rodolfo Zanella

Although Au and Ru are not miscible in the bulk, the paper focusses on the attempts to prepare bimetallic Au-Ru/TiO2 catalysts by deposition-precipitation with urea (co-DPU and sequential DPU, Au then Ru and vice versa). Gold was found already reduced after the preparations of co-DPU and Ru then Au…

Effects of dealumination on the performance of Ni-containing BEA catalysts in bioethanol steam reforming

Wojciech Gac, Magdalena Greluk, Grzegorz Słowik, Yannick Millot, Laetitia Valentin, Stanislaw Dzwigaj

The effects of dealumination of BEA zeolite on the formation of nickel active sites and the performance of Ni-containing BEA zeolite catalysts in the steam reforming of ethanol have been studied. Ni-containing BEA zeolite catalysts were prepared by the impregnation of unmodified and dealuminated…

Partial oxidation of methane over bifunctional catalyst I. In situ formation of Ni0/La2O3 during temperature programmed POM reaction over LaNiO3 perovskite

Tri Huu Nguyen, Agata Łamacz, Patricia Beaunier, Sylwia Czajkowska, Marian Domański, Andrzej Krztoń, Tiep van Le, Gérald Djéga-Mariadassou

The transformation of perovskite to an oxide-supported metal during reaction of partial oxidation of methane (POM) has been very often cited in literature as the “reduction” of the perovskite, without any detailed mechanism. In this work, the in situ transformation of initial LaNiO3 perovskite to…

Low temperature dry reforming of methane on rhodium and cobalt based catalysts: active phase stabilization by confinement in the mesoporous SBA-15

N. El Hassan, M.N. Kaydouh, H. Geagea, H. Elein, Karam Jabbour, S. Casale, H El Zakhem, Pascale Massiani

Two silica supports either non porous (SiO2) or mesoporous (SBA-15) were impregnated with cobalt (12 wt%) in order to study the confinement effect on catalytic performances in dry reforming of methane. Further increase of activity was obtained by adding small amounts of rhodium (0.2 and 0.5 wt%) to…

Core–Shell Gold/Silver Nanoparticles for Localized Surface Plasmon Resonance-Based Naked-Eye Toxin Biosensing

Alexis Loiseau, Lu Zhang, David Hu, Michèle Salmain, Yacine Mazouzi, Raphaël Flack, Bo Liedberg, Souhir Boujday

The localized surface plasmon resonance (LSPR) phenomenon provides a versatile property for biodetection. Herein, this unique feature was employed to build a homogeneous optical biosensor to detect staphylococcal enterotoxin A (SEA) in solution down to very low levels by naked-eye readout. If the…

Silk Polymers and Nanoparticles: A Powerful Combination for the Design of Versatile Biomaterials

Cristina Belda Marín, Vincent Fitzpatrick, David Kaplan, Jessem Landoulsi, Erwann Guénin, Christophe Egles

Silk fibroin (SF) is a natural protein largely used in the textile industry but also in biomedicine, catalysis, and other materials applications. SF is biocompatible, biodegradable, and possesses high tensile strength. Moreover, it is a versatile compound that can be formed into different materials…

Critical assessment of solvent effects on absorption and fluorescence of 3HF in acetonitrile in the QM/PCM framework: A synergic computational and experimental study

Daniele Loco, Stefano Protti, Benedetta Mennucci, Alberto Mezzetti

Absorption and fluorescence properties of 3-hydroxyflavone (3HF) dissolved in the polar aprotic solvent acetonitrile have been investigated by electronic spectroscopies, associated to mixed quantum mechanical (QM)/classical calculations, where the effect of the solvent is included at the classical…

Mpfunzeni Raphulu, Thabang Ntho, Pumeza Gqogqa, John Moma, Lebohang Mokoena, Gary Pattrick, Mike Scurrell, Laurent Delannoy, Catherine Louis

A thorough characterisation of Au/TiO2 and Au/ FeOx-TiO2 catalysts was conducted in order to get a better understanding of the effect of Fe on the Au/TiO2 catalysts and link it to differences observed in their activities for CO oxidation. Several techniques including HRTEM, temperature-programmed…
