Unravelling surface changes on Cu-Ni alloy upon immersion in aqueous media simulating catalytic activity of aerobic biofilms

Nesrine Aissaoui, Irma Liascukiene, Michel Genet, Christine Dupont-Gillain, Karim El Kirat, Caroline Richard, Jessem Landoulsi

Cu-Ni alloys are extensively used in contact with natural waters and are impacted by microbial activities of biofilms. The mechanisms by which surface changes occur upon immersion remain not well understood. Herein, an aerobic microbial activity of natural biofilms is mimicked by the enzymatic…

Isopropanol Dehydration on Amorphous Silica–Alumina: Synergy of Brønsted and Lewis Acidities at Pseudo-Bridging Silanols

Kim Larmier, Céline Chizallet, Sylvie Maury, Nicolas Cadran, Johnny Abboud, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

The mechanism of isopropanol dehydration on amorphous silica–alumina (ASA) was unraveled by a combination of experimental kinetic measurements and periodic density functional theory (DFT) calculations. We show that pseudo-bridging silanols (PBS-Al) are the most likely active sites owing to the…

Formation and fate of alpha-dicarbonyl compounds in honey and Maillard model systems

Varoujan A. Yaylayan, Eric Marceau, Fong L. Chu

Reactive alpha-dicarbonyl compds. can originate from various sources contg. reducing sugars. They are responsible for the formation of many important Maillard reaction products generated in food. Some alpha-dicarbonyl compds. are assocd. with toxicity and immunosuppressive effects while others with…

Different Kinds of Tetrahedral V Species in Vanadium-Containing Zeolites Evidenced by Diffuse Reflectance UV-vis, Raman, and Periodic Density Functional Theory

Anna E. Lewandowska, Miguel A. Banares, Frederik Tielens, Michel Che, Stanislaw Dzwigaj

The combined use of DR-UV-vis and Raman spectroscopies allows one to evidence three kinds of tetrahedral V-V with different structure in V(x)SiBEA zeolite. In all cases, vanadium species possess distorted tetrahedral configuration. At very low vanadium content (0.05 wt %), the majority of…

In Situ Generation of Active Pd Nanoparticles within a Macroreticular Acidic Resin: Efficient Catalyst for the Direct Synthesis of Hydrogen Peroxide

Kohsuke Mori, Akihiro Hanafusa, Michel Che, Hiromi Yamashita

An acidic resin bearing SO3H functional groups within its reticular structure acts as an efficient support for the in situ formation of highly active Pd nanoparticles (NPs) responsible for the direct synthesis of hydrogen peroxide from H2 and O2. Characterization by means of X-ray absorption fine…

Monitoring of the state of silver in porous oxides during catalyst preparation

Elie Sayah, Dalil Brouri, Anne Davidson, Pascale Massiani

Silver-supported porous oxides are promising heterogeneous catalysts for air treatment. Classical ways of prepn. are incipient wet impregnation or ion exchange (in case of zeolites) of a support with silver nitrate. Nevertheless, this precursor is known for its photosensitivity. The latter can lead…
