On the origin of the optimum loading of Ag on Al2O3 in the C3H6-SCR of NOx

Tesnim Chaieb, Laurent Delannoy, Catherine Louis, Cyril Thomas

Ag/Al2O3 catalysts synthesized by the common impregnation technique with various Ag loadings were characterized by the NOx-Temperature-Programmed Desorption (TPD) method and their catalytic performances were evaluated in the selective catalytic reduction of NOx by propene (C3H6-SCR). It was found…

Improved activity and stability in CO oxidation of bimetallic Au-Cu/TiO2 catalysts prepared by deposition-precipitation with urea

A. Sandoval, Catherine Louis, Rodolfo Zanello

Au-Cu bimetallic catalysts supported on TiO2 were prepared for the first time by sequential deposition-precipitation with the urea method, copper first then gold. Au-Cu catalysts with four different Au:Cu atomic ratios were synthesized (1:0.4 to 1:1.2). This method allowed quantitative deposition…

Nanoscale antiadhesion properties of sophorolipid-coated surfaces against pathogenic bacteria

Claire Valotteau, Niki Baccile, Vincent Humblot, Sophie Roelants, Wim Soetaert, Christian V Stevens, Yves Dufrêne

A current challenge in nanomedicine is to develop innovative strategies to fight infections caused by multiresistant bacterial pathogens. A striking example is antiadhesion therapy, which represents an attractive alternative to antibiotics to prevent and treat biofilm-associated infections on…

Synthesis of metal oxide catalysts

Xavier Carrier, Sébastien Royer, E. Marceau

This chapter gives an overview of the current preparation strategies for the synthesis of bulk and supported metal oxide catalysts, in order to give rational guides to understand the synthetic challenges associated with the preparation of these catalytic systems developed in the successive chapters…

Surface orientation dependent interaction of cobalt (II) precursors with alpha-alumina

Céline Chizallet, Christian Schlaup, Emiliano Fonda, Xavier Carrier

The performances of alumina-supported cobalt catalysts strongly depend on Co/alumina interactions, that are poorly understood. In the present work, α-alumina surfaces are used as models of polycrystalline support, to unravel their orientation dependent behavior by GI-EXAFS. The CoII/α-alumina…

Compared activity and stability of three Ni-silica catalysts for methane bi- and dry reforming

Karam Jabbour, M.N. Kaydouh, N El Hassan, H El Zakhem, Sandra Casale, Anne Davidson, Pascale Massiani

A low weight % of Ni (5 wt %) and the two solvents technique of deposition are used to obtain well-dispersed Ni-species (either particles or species dispersed on the silica surface) and avoid the formation of large particles on three silicas SBA-15, Aerosil 300 and diatoms MN3. Stability tests at…

Co–Ru Nanoalloy Catalysts for the Acceptorless Dehydrogenation of Alcohols

Brandon Azeredo, Tayssir Ben Ghzaiel, Ning Huang, Kamila Kaźmierczak, Wenjie Shen, Guillaume Wang, Delphine Schaming, Patricia Beaunier, Philippe Decorse, Noémie Perret, Jennifer Peron, Marion Giraud, Carine Michel, Lorette Sicard, Jean-Yves Piquemal

The synthesis of Co–Ru bimetallic nanoparticles was performed by co-reduction of Co(II) and Ru(III) salts in octan-1-ol, acting both as a solvent and a mild reducing agent. The metal composition was varied in the entire range, from pure Co to pure Ru. Although Co and Ru are miscible in the bulk,…

Stabilisation of small mono- and bimetallic gold–silver nanoparticles using calix[8]arene derivatives

Priyanka Ray, Marie Clément, Cyril Martini, Ibrahim Abdellah, Patricia Beaunier, José-Luis Rodriguez-Lopez, Vincent Huc, Hynd Remita, Isabelle Lampre

In this paper, we report the synthesis of octa(hydroxy)-octa(mercaptobutoxy)calix[8]arene and its use as a stabiliser of nanoparticles (NPs). We show that the reduction of gold and/or silver ions in the presence of this calix[8]arene in ethanolic solutions leads to the formation of very small…
