Influence of the nature and environment of vanadium in VSiBEA zeolite on selective catalytic reduction of NO with ammonia

R. Baran, T. Onfroy, T. Grzybek, S. Dzwigaj

The influence of the nature and environmental of vanadium on the catalytic properties of VxSiBEA zeolite in selective catalytic reduction of NO with ammonia is investigated. Catalysts containing 1-7.5 wt.% of vanadium were prepared by a two-step postsynthesis method which consists, in the first…

Building of an immunosensor : how can the composition and structure of the thiol attachment layer affect the immunosensor efficiency ?

Elisabeth Briand, Michèle Salmain, Jean-Marie Herry, Hubert Perrot, Chantal Compere, Claire-Marie Pradier

Immunosensors, based on the immobilsation of model rabbit antibodies on a mixed self assembled monolyaers and Protein A as a linking agent on gold transducers, were elaborated and characterised at each step by Modulated polarisation- Infrared Spectroscopy (PM-IRRAS) and punctually by Atomic Force…

In-situ monitoring of transition metal complex adsorption on oxide surfaces during the first stages of supported metal catalyst preparation

Juliette Blanchard, Antoine Hervier, Guylène Costentin, John Regalbuto, Catherine Louis, Souhir Boujday

In the preparation of supported catalysts by deposition, in solution, of a transition metal complex (TMC) on an oxide support, the interactions occurring at the solid/liquid interface between the TMC and the oxide have a crucial impact on the properties of the final catalyst. However, these…

Tuning the shape and size of hybrid gold nanoparticles by porphyrins using seed-mediated synthesis

Jolanda Spadavecchia, Sandra Casale, Jessem Landoulsi, Claire-Marie Pradier

We report the synthesis of hybrid gold nanostructures by means of seed/growth approach, using porphyrin molecules (protoporphyrin IX) in addition to cetyltetraammonium bromide (CTAB) as surfactants and/or shape-modulating agents. The combination of CTAB and porphyrin yields stable complexes that…

Partial oxidation of methane over bifunctional catalyst I. In situ formation of Ni0/La2O3 during temperature programmed POM reaction over LaNiO3 perovskite

Tri Huu Nguyen, Agata Łamacz, Patricia Beaunier, Sylwia Czajkowska, Marian Domański, Andrzej Krztoń, Tiep van Le, Gérald Djéga-Mariadassou

The transformation of perovskite to an oxide-supported metal during reaction of partial oxidation of methane (POM) has been very often cited in literature as the “reduction” of the perovskite, without any detailed mechanism. In this work, the in situ transformation of initial LaNiO3 perovskite to…

Walking peptide on Au(110) surface: Origin and nature of interfacial process

V. Humblot, A. Tejeda, J. Landoulsi, A. Vallée, A. Naitabdi, Ahmed Taleb, C.-M. Pradier

IGF tri-peptide adsorption on Au(110)-(1 × 2) under Ultra High Vacuum (UHV) conditions has been investigated using surface science techniques such as synchrotron based Angle Resolved X-ray Photoemission Spectroscopy (AR-PES or AR-XPS), Low Energy Electron Diffraction (LEED) and Scanning Tunnelling…

A comparative in situ TEM and UV-visible spectroscopic study of the thermal evolution of Ag species dispersed on Al2O3 and NaX zeolite supports

Elie Sayah, Dalil Brouri, Pascale Massiani

The oxidation states and dispersion of silver supported on alumina and faujasite were monitored by TEM, TPR and in situ UV-visible spectroscopy along the steps of thermal dehydration, then oxidation and finally reduction of the freshly prepared materials. An original transmission electron…

Selectivity in the gas-phase hydrogenation of 4-nitrobenzaldehyde over supported Au catalysts

Noémie Perret, Xiaodong Wang, Thomas Onfroy, Christophe Calers, Mark A Keane

The effects of Au particle size and support properties have been examined in the gas-phase hydrogenation of 4-nitrobenzaldehyde over Au/ZrO2, Au/TiO2 and Au/Al2O3. Gold particle size was varied using deposition-precipitation and impregnation syntheses. The catalysts have been characterised in terms…

Unraveling the Direct Decomposition of NO x over Keggin Heteropolyacids and Their Deactivation Using a Combination of Gas-IR/MS and In Situ DRIFT Spectroscopy

Josefine Schnee, Laurent Delannoy, Guylène Costentin, Cyril Thomas

Keggin heteropolyacids (HPAs) have been known to be efficient NOx absorbers for many years, and to decompose a significant fraction of the NOx species pre-absorbed at 100-150 °C into harmless N2 and O2 upon rapid heating to 450 °C. However, this capability of Keggin HPAs to directly decompose NOx…
