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…

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…

Use of unconventional activation methods for the oxidative cleavage of lignin by dioxygen, Utilisation de moyens d’activation non-conventionnels pour le clivage oxydant de la lignine par le dioxygène

Louay Al-Hussaini

Due to the depletion of fossil resources, the interest of lignin as a sustainable alternative to petroleum is growing. Thus, the main purpose of this thesis was to develop a process for oxidative cleavage of lignin by dioxygen that involves unconventional methodologies like sonochemistry and ball-…, Du fait de l'épuisement des ressources fossiles, l'intérêt de la lignine en tant qu'alternative durable est grandissant. Ainsi, le but principal de cette thèse était de mettre au point un procédé de clivage oxydant de la lignine par le dioxygène qui implique des voies non…

Defects in ZnO nanoparticles obtained by gas-phase syntheses, Défauts dans les nanoparticules de ZnO obtenues par synthèses en phase gazeuse

Miao Zhang

By far, the assignment of defects-related spectroscopic features of zinc oxide is still a matter of great controversy. This is probably due to the variety of possible defects in ZnO as well as to their still uncertain formation energies and positions within the band gap. Uncontrolled measurement…, L’attribution des signatures spectrales liées aux défauts dans l’oxyde de zinc fait encore l’objet de controverses. Ceci est probablement dû à la grande variété de défauts possibles, à l’incertitude de leur niveau d’énergie ainsi que leur énergie de formation dans la bande interdite. De plus, l’…

Current Progress in Aqueous Corrosion of Multi-Principal Element Alloys

M. Ghorbani, Z. Li, Y. Qiu, P. Marcus, J. Scully, Oumaïma Gharbi, H. Luo, R. Gupta, Z. Zeng, H. Fraser, M. Taheri, N. Birbilis

While multi-principal element alloys (MPEAs) remain a promising class of materials owing to several attractive mechanical properties, their corrosion performance is also unique. In this concise review, we present an emerging overview of some of the general features related to MPEA corrosion,…

The controlled synthesis of metal-acid bifunctional catalysts: The effect of metal:acid ratio and metal-acid proximity in Pt silica-alumina catalysts for n-heptane isomerization

Jadid E Samad, Juliette R Blanchard, Celine R Sayag, Catherine R Louis, John R Regalbuto

Several series of metal-acid bifunctional catalysts with controlled metal:acid ratios and metal site-acid site proximity were evaluated for n-heptane isomerization. Through the study of metal deposition reported in the companion paper, proximity could be achieved at four distinct scales: atomic,…

Insights into the WOx Coverage-Dependent Location and Oxidation State of Noble Metals Supported on Tungstated Oxides: The Case of Rh/WOx−Ce0.62Zr0.38O2

Thomas Bonnotte, Rachel P. Doherty, Céline Sayag, Jean-Marc Krafft, Christophe Méthivier, Mickaël Sicard, Frédéric Ser, Cyril Thomas

Noble metals-promoted tungstated oxides have been shown to be profitable in a wide variety of catalytic reactions of environmental interest but to be detrimental in the hydrogenation of aromatics. The origin of the deleterious effect of tungstates on the hydrogenation performance of noble metals is…

Preparation of Supported Gold Nanoparticles by a Modified Incipient Wetness Impregnation Method

Laurent Delannoy, Nissrine El Hassan, Andrea Musi, Nga Nguyen Le To, Jean-Marc Krafft, Catherine Louis

In this work, we show that if the mere procedure of impregnation of oxide supports with chloroauric acid, which is well-known to lead to large gold particles, is followed by a step of washing with ammonia, small gold particles (3-4 nm) can be obtained after a treatment of calcination at 300 °C on…
