Plasma Assisted Catalyst for NOx Remediation from Lean Gas Exhaust

Ahmed Khacef, Patrick da Costa, Gérald Djéga-Mariadassou

A non-thermal plasma (NTP) reactor was coupled with a three-function catalyst in order to verify the nature of the effect of the plasma on the catalytic process. A mixture of NO/O2/hydrocarbons in N2 was used as a lean model exhaust gas composition. The plasma was found to perform two of the three…

LRS-1, a new delaminated phyllosilicate material with high acidity », Chem. Mater., 18(1), 34-40 (2006).

Bachar Zebib, Jean-François Lambert, Juliette Blanchard, Michèle Breysse

Well-crystallized samples of the phyllosilicate magadiite have been synthesized in their sodic form, both purely silicic and with an Al/Si ratio of 30. They have been delaminated by a procedure consisting of CTMA+ swelling in the presence of TPAOH, sonication, and calcination at 700°C to remove the…

Selective gas phase hydrogenation of nitroarenes over Mo 2 C-supported Au-Pd

Xiaodong Wang, Noémie Perret, Laurent Delannoy, Catherine Louis, Mark A. Keane

We report the first synthesis of Mo2C-supported Au and Au–Pd catalysts (nominal Au/Pd = 10 and 30) obtained from colloidal nanoparticles stabilised by polyvinyl alcohol (PVA). Equivalent Au/Al2O3 and Au–Pd/Al2O3 were prepared and served as benchmarks. Residual PVA was removed by thermal treatment…

Chemical Modifications of Au/SiO2 Template Substrates for Patterned Biofunctional Surfaces

Elisabeth Briand, Vincent Humblot, Jessem Landoulsi, Sarunas Petronis, Claire-Marie Pradier, Bengt Kasemo, Sofia Svedhem

The aim of this work was to create patterned surfaces for localized and specific biochemical recognition. For this purpose, we have developed a protocol for orthogonal and material-selective surface modifications of microfabricated patterned surfaces composed of SiO2 areas (100 mu m diameter)…

Promoting Ag/Al2O3 Performance in Low-Temperature H2-C3H6-SCR by Thermal Pretreatment of γ-Alumina in Water

Tesnim Chaieb, Laurent Delannoy, Catherine Louis, Cyril Thomas

The present work highlights for the first time that a thermal treatment of γ-Al2O3 in water at 80 °C for 24 h prior to Ag deposition (Ag/Al2O3-OH) leads to a drastic enhancement of H2-C3H6-SCR performance at low temperature. This enhancement is attributed to the higher NOx coverage on Ag/Al2O3-OH…

Catalysis assisted by plasmon, Catalyse assistée par plasmon

Iyad Sarhid

Metallic nanoparticles (NPs) have many applications in catalysis. Some of them (gold, silver, copper) have a visible absorption resulting from the excitation of the surface plasmon by an external electromagnetic field. In this project, we propose to couple the catalytic properties of gold-based…, Les nanoparticules (NPs) métalliques ont de nombreuses applications en catalyse. Certaines d’entre elles (or, argent, cuivre) présentent une absorption dans le visible résultant de l’excitation du plasmon de surface par un champ électromagnétique extérieur.
