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…

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…

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…

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…

A New Nanocomposite: L-DOPA/Laponite

Maguy Jaber, Jean-Francois Lambert

A simple procedure is reported to obtain original nanocomposite materials combining the smectite Laponite and melanin-like polymers. Aq. polymn. of L-DOPA is considerably accelerated in the presence of suspended Laponite particles, and its mechanism is significantly modified with respect to…
