A Study of Cobalt Speciation in Co/Al2O3 Catalysts Prepared from Solutions of Cobalt-Ethylenediamine Complexes

François Dumond, Eric Marceau, Michel Che

The thermal reduction of Co/Al2O3 catalysts prepared by impregnation of Co(II) nitrate generally leads to migration of cobalt ions into alumina with formation of cobalt aluminate. In order to prevent the latter, it is attempted to reduce cobalt by decomposition of supported precursor salts…

Ab initio study of the hydroxylated surface of amorphous silica : a representative model.

Frederik Tielens, Christel Gervais, Jean François Lambert, Francesco Mauri, Dominique Costa

A new complete, representative model for the hydroxylated surface of amorphous silica is presented and characterized by means of periodic DFT calculations. This model accounts for the experimentally encountered ring size distribution, Si-O-Si and O-Si-O angles, silanols density, and distribution (…

Influence of the nature of the reducible support on CO oxidation kinetics of supported Rhd+ catalysts: SnO2 versus Ce0.68Zr0.32O2

Céline Fontaine-Gautrelet, Cyril Thomas, Gérald Djéga-Mariadassou

CO-O2 kinetics was studied on Rh(0.3wt%)/SnO2 and compared with that reported previously on Rh/Ce0.68Zr0.32O2. The lower oxygen mobility on SnO2 and the stronger bonding of CO with the RhΔ+ sites of Rh/SnO2, are suggested to account for the lower CO oxidation activity of Rh/SnO2 compared with that…

From Al2O3-supported Ni(II)-ethylenediamine Complexes to CO Hydrogenation Catalysts: Importance of the Hydrogen Post-treatment Evidenced by XPS

Fabien Négrier, Eric Marceau, Michel Che, Jean-Marc Giraudon, Léon Gengembre, Axel Löfberg

Ni (7 wt%)/Al2O3 catalysts prepared by decomposition of Ni(II)-ethylenediamine complexes in inert atmosphere initially contain a mixture of metallic and oxidized nickel. X-ray photoelectron spectroscopy shows that after a hydrogen treatment at 500°C, the system contains more metallic nickel than…

Investigation of new routes for the preparation of mesoporous calcium oxide supported nickel materials used as catalysts for methane dry reforming reaction

Ola El Samrout, Leila Karam, Karam Jabbour, Pascale Massiani, Franck Launay, Nissrine El Hassan

Nowadays, one of the metal oxides attracting significant attention in catalysis is calcium oxide (CaO) because it is cheap, environmentally friendly and characterized by a strong basic character. These distinctive properties make CaO promising in a wide range of industrial applications such as…
