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…

Theoretical and experimental study of the adsorption of neutral glycine on silica from the gas phase

Claire Lomenech, Gregoire Bery, Dominique Costa, Lorenzo Stievano, Jean-François Lambert

The adsorption of neutral glycine onto amorphous silica was investigated both theoretically and experimentally. DFT calculations were performed at the BLYP-631++G** level using a cluster approach. Several possible configurations involving the formation of H-bonds between glycine and one, two or…

Comprehension of cellulose depolymerisation mechanisms induced by iron ions, Compréhension des mécanismes de dépolymérisation de la cellulose induits par les ions fer

Alice Gimat

Degradation of paper by iron gall inks (IGI) is a challenging issue for written heritage conservation. These inks consist of a mixture of iron(II) sulphate, tannins and gum Arabic, and are therefore acidic and iron-rich. Hence, paper degradation by IGI is often attributed to a combination of acid…, La dégradation du papier par les encres ferrogalliques (EFG) est un défi pour la conservation du patrimoine écrit. Ces encres, composées d'un mélange de sulfate de fer (II), de tannins et de gomme Arabique, sont acides et riches en fer. Par conséquent, les mécanismes de dégradation des…

Experimental clues for detecting biosignatures on Mars

J.-C. Viennet, S. Bernard, Corentin Le Guillou, P. Jacquemot, E. Balan, L. Delbes, B. Rigaud, T. Georgelin, M. Jaber

Forthcoming exploration of Mars aims at identifying fossil biosignatures within ancient clay-rich formations. The subsurface of Mars has mostly acted as a giant freezer for the last 4 Gyr, thereby preserving potential remains of martian life. Yet, volcanism and impactors have periodically triggered…
