The controlled synthesis of metal-acid bifunctional catalysts: Selective Pt deposition and nanoparticle synthesis on amorphous aluminosilicates

Jadid E. Samad, Juliette Blanchard, Celine Sayag, Catherine Louis, John R. Regalbuto

The rational synthesis of metal-acid bifunctional catalysts based on aluminosilicates will involve control over which domain – alumina or silica – the metal can be deposited on, as well as the control of particle size. These factors determine the ratio and proximity of the metal and acid sites. The…

Enhanced selectivity of 3-D ordered macroporous Pt/Al2O3 catalysts in nitrites removal from water

A.C. Sunil Sekhar, A. Zaki, S. Troncea, S. Casale, C.P. Vinod, J.P. Dacquin, P. Granger

Tailored macroporous mesoporous alumina supports have been successfully prepared using a single hard templating approach. Pt nanoparticles, showing similar physico-chemical properties, were homogeneously dispersed throughout the different alumina frameworks as catalytic active phase for drinking…

Identification and Location of Iron Species in Fe/SBA-15 Catalysts: Interest for Catalytic Fenton Reactions

Cécile Cornu, Jean-Luc Bonardet, Sandra Casale, Anne Davidson, Sebastien Abramson, Gilles André, Florence Porchet, Ivana Grcic, Vesna Tomasic, Dinko Vujevic

We have used a single SBA-15 silica batch (mesopore diameter of 7.1 nm) and the two-solvent impregnation technique with either pentane or cyclohexane to prepare model samples in which an initial aqueous solution of salt precursor (iron nitrate or iron chloride) is deposited mainly inside silica…

Potent antimicrobial peptides against Legionella pneumophila and its environmental host, Acanthamoeba castellanii.

Margot Schlusselhuber, Vincent Humblot, Sandra Casale, Christophe Méthivier, Julien Verdon, Matthias Leippe, Jean-Marc Berjeaud

Legionella pneumophila, the major causative agent of Legionnaires' disease, is most often found in the environment in close association with free-living amoebae, leading to persistence, spread, biocide resistance, and elevated virulence of the bacterium. In the present study, we evaluated the…

Co-grafting of antiadhesive and antimicrobial agents onto UV-micropatterned copper surfaces

Jessie Peyre, Vincent Humblot, Christophe Méthivier, Jean-Marc Berjeaud, Claire-Marie Pradier

Adhesion of proteins and bacteria was reduced by a factor close to one order of magnitude, and adhered bacteria were dramatically damaged on copper surfaces by grafting a PEG-modified PMMA-based (polymethyl methacrylate) copolymer together with an antimicrobial peptide. To obtain PEG and a peptide…

Electron transfers in a TiO₂-containing MOR zeolite: Synthesis of the nanoassemblies and application using a probe chromophore molecule

A. Legrand, A. Moissette, M. Hureau, S. Casale, P. Massiani, H. Vezin, A.S. Mamede, I. Batonneau-Gener

New assemblies constituted by a microporous matrix of mordenite (MOR) zeolite on which TiO₂ nanoclusters are deposited were synthesized using ionic oxalate complexes and TiCl₃ titanium precursors. The samples were used to investigate the transfer of…

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…

Comparison of molybdenum carbide and tungsten carbide for the hydrodesulfurization of dibenzothiophene

Agnieszka Szymanska-Kolasa, Marek Lewandowski, Celine Sayag, G. Djéga-Mariadassou

The molybdenum and tungsten carbides (Mo2C and W2C) were synthesized, characterized and tested in hydrodesulfurization (HDS) of dibenzothiophene (DBT). The phase purity of these catalysts was established by X-ray diffraction (XRD), and the surface properties were determined by N2 BET specific…
