Ordered mesoporous “one-pot” synthesized Ni-Mg(Ca)-Al2O3 as effective and remarkably stable catalysts for combined steam and dry reforming of methane (CSDRM)

Karam Jabbour, Pascale Massiani, Anne Davidson, Sandra Casale, Nissrine El Hassan

Two series of Nix% (x: 5–10 wt%) and Ni5%M5% (M: Ca or Mg) containing mesoporous Al2O3 catalysts were prepared by “one-pot” synthesis following an evaporation-induced self-assembly (EISA) method. After reduction, the catalysts showed very high Ni dispersion within the structured oxide matrix giving…

Adsorption of chiral molecules in oxide-supported heterogeneous catalysts : a model approach, Adsorption de molécules chirales sur catalyseurs hétérogènes supportés sur oxyde : une approche modèle

Elisa Meriggio

Enantioselective heterogeneous catalysis is a method of choice for the synthesis of enantiopure chiral products. One current approach involves the modification of a metal surface by a chiral modifier. Despite its great potential, only a small number of successful systems have been developed so far…, La catalyse asymétrique hétérogène est une méthode de choix pour la synthèse de composés chiraux énantiopurs. Une approche courante implique la modification d'une surface métallique par un inducteur chiral. Malgré son potentiel, seul un petit nombre de systèmes ont été mis au point jusqu'…

Gold Nanoparticles on Oxide-Free Silicon-Molecule Interface for Single Electron Transport

Louis Caillard, Oliver Seitz, Philip M. Campbell, Rachel P. Doherty, Anne-Félicie Lamic-Humblot, Emmanuelle Lacaze, Yves J. Chabal, Olivier Pluchery

Two different organic monolayers were prepared on silicon Si(111) and modified for attaching gold nanoparticles. The molecules are covalently bound to silicon and form very ordered monolayers sometimes improperly called self-assembled monolayers (SAM). They are designed to be electrically…

Oxidation of gold metal particles supported on TiO2: an FTIR study by means of low-temperature CO adsorption

Hr. Klimev, Katia Fajerwerg, K. Chakarova, L. Delannoy, C. Louis, K. Hadjiivanov

Two Au/TiO2 samples with different gold loadings (0.7 and 4.0 wt.% Au) were prepared by deposition-precipitation with urea and calcined at 673 K. TEM revealed gold particles of 3.2 and 3.9 nm for the 0.7 and 4.0 wt.% samples, respectively. The samples were subjected to different red-ox treatments…

Dispersion assessment of H3PMo12O40 supported on TiO2 through in situ IR upon pyridine adsorption

Alixandre Magerat, Laetitia Valentin, Alexandre Vimont, Sophie Hermans, Eric M Gaigneaux, Josefine Schnee

Keggin heteropolyacids (HPAs) are powerful catalytic materials because of their particularly high acid strength. Dispersing them on a support is a commonly adopted strategy to overcome their low specific surface area and increase their recoverability. In this regard, their dispersion needs to be…
