Physico-chemical properties of FeAlBEA and FeSiBEA zeolites and their catalytic activity in the SCR of NO with ethanol or methane

Janusz Janas, Stanislaw Dzwigaj

FeAlBEA and FeSiBEA zeolites are prepared by a conventional ion exchange and a two-step postsynthesis method, respectively. Their physico-chemical properties are investigated by XRD, FTIR, and diffuse reflectance UV-vis. For FeAlBEA zeolite, framework tetrahedral Fe(III), extra-framework octahedral…

Effect of vanadium dispersion and of support properties on the catalytic activity of V-containing silicas

Marco Piumetti, Barbara Bonelli, Pascale Massiani, Stanislaw Dzwigaj, Ilenia Rossetti, Sandra Casale, Marco Armandi, Cyril Thomas, Edoardo Garrone

Two V-SBA-15 and V-MCF materials (containing about 2.5 wt.% vanadium) were prepared by direct synthesis and tested as catalysts in the decomposition of the most stable chlorinated-alkane, dichloromethane (a total oxidation reaction) and in the oxidative dehydrogenation (ODH) of propane (a partial…

Adsorption of L-Lysine on Cu(110): A RAIRS study from UHV to the liquid phase

Vincent Humblot, Christophe Méthivier, Claire-Marie Pradier

Adsorption of L-Lysine on a Cu(110) surface has been investigated under UHV condition from sublimation of a crystalline phase. The adsorption was characterised by Fourier Transform Reflection Absorption Infrared Spectroscopy (FT-RAIRS) during exposure and Auger Electron Spectroscopy (AES). At room…

Sorption of Cu(II) onto vineyard soils: macroscopic and spectroscopic investigations

Eric Marceau, Lorenzo Stievano

The sorption of Cu on five vineyard soils was examined via macroscopic and spectroscopic investigations. The composition of the soils was previously determined using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). X-ray absorption spectroscopy (XAS) was employed to determine the…

A DNA biosensor based on peptide nucleic acids on gold surfaces

Eva Mateo-Marti, C. Briones, Claire-Marie Pradier, Jose A. Martin-Gago

We present a DNA biosensor based on self assembled monolayers (SAMs) of thiol-derivatized Peptide nucleic acid (PNA) chains adsorbed on gold surfaces for recognizing complementary ssDNA. PNA molecules tend to realign their molecular axes parallel to the surface normal and form SAMs on gold surfaces…

Kinetic study of the deep hydrodesulfurization of dibenzothiophene over molybdenum carbide supported on a carbon black composite: Existence of two types of active sites

A. Hynaux, Celine Sayag, S. Suppan, J. Trawczynski, M. H. Lewandowski, A. Szymanska-Kolasa, G. Djéga-Mariadassou

Hydrodesulfurization (HDS) is part of the hydrotreating process, which is an ensemble of several reactions (HDN, HDO, HDS, etc.) taking place simultaneously at the industrial scale. Only sulfur is currently submitted to drastic Europeans specifications and conventional commercial catalysts cannot…

Carbon black composites—supports of HDS catalysts

P. Gheek, S. Suppan, J. Trawczynski, A. Hynaux, Celine Sayag, G. Djéga-Mariadassou

HDS activity of sulfided Mo (W) catalysts supported on carbon black composites (CBC) is affected by kind of functional groups present on the CBC surface. Oxidation of CBC with (NH4)2S2O8 produce functionalities with the highest acid strength and corresponding catalyst exhibits the highest HDS…
