Exploring the self-assembly of dumbbell-shaped polyoxometalate hybrids, from molecular building units to nanostructured soft materials

Mireia Segado Centellas, Madeleine Piot, Raphaël Salles, Anna Proust, Ludovic Tortech, Dalil Brouri, Sébastien Hupin, Benjamin Abécassis, David Landy, Carles Bo, Guillaume Izzet

The formation of hierarchical nanostructures using preformed dumbbell-like species made of covalent organic–inorganic polyoxometalate (POM)-based hybrids is herein described. In this system, the presence of charged subunits (POM, metal linkers, and counter ions) in the complex molecular…

Hollow Gold Nanoshells for Sensitive 2D Plasmonic Sensors

Daoming Sun, Ferdaous Ben Romdhane, Axel Wilson, Michèle Salmain, Souhir Boujday

The interaction of incident light with noble metal nanoparticles engenders a fascinating phenomenon known as localized surface plasmon resonance (LSPR). This results in the presence of single or multiple intense absorption bands in the visible to near-infrared spectral range whose position is…

Charge transport through redox active [H₇P₈W₄₈O₁₈₄]^33- polyoxometalates self-assembled onto gold surfaces and gold nanodots

K. Dalla Francesca, Stéphane Lenfant, M. Laurans, F. Volatron, G. Izzet, Vincent Humblot, C. Methivier, David Guérin, A. Proust, Dominique Vuillaume

Polyoxometalates (POMs) are redox-active molecular oxides, which attract growing interest for their integration into nano-devices, such as high-density data storage non-volatile memories. In this work, we investigated the electrostatic deposition of the negatively charged [H7P8W48O184]33− POM onto…

Aqueous nickel(II) hydroxycarbonate instead of nickel(0) colloids as precursors of stable Ni-silica based catalysts for the dry reforming of methane

Oscar Daoura, Ghenwa El Chawich, Maya Boutros, Nissrine El Hassan, Pascale Massiani, Ovidiu Ersen, Walid Baaziz, Franck Launay

Nickel(II) hydroxycarbonate colloids were synthesized in water by the reaction of nickel(II) with carbonate in the presence of hexadecyltrimethylammonium bromide. Then, they were dispersed onto SBA-15 affording, after calcination and reduction, a supported 3 wt% nickel(0) catalyst for the dry…

Comparison of molybdenum carbide and tungsten carbide for the hydrodesulfurization of dibenzothiophene

Agnieszka Szymanska-Kolasa, Marek Lewandowski, Celine Sayag, G. Djéga-Mariadassou

The molybdenum and tungsten carbides (Mo2C and W2C) were synthesized, characterized and tested in hydrodesulfurization (HDS) of dibenzothiophene (DBT). The phase purity of these catalysts was established by X-ray diffraction (XRD), and the surface properties were determined by N2 BET specific…

Transformations of γ-alumina in aqueous suspensions. 1. Alumina chemical weathering studied as a function of pH

Xavier Carrier, Eric Marceau, Jean-François Lambert, Michel Che

Hydration of γ-Al2O3 is often reported to occur via the superficial transformation of the alumina surface into alumina hydroxide-like layers. However, very little evidence has been given so far to support this hypothesis. It is demonstrated here by X-ray diffraction, TEM, electron diffraction and…

ADSORPTION ON STAINLESS STEEL SURFACES OF BIOSURFACTANTS PRODUCED BY GRAM-NEGATIVE AND GRAM-POSITIVE BACTERIA : CONSEQUENCE ON THE BIOADHESIVE BEHAVIOR OF PATHOGENIC STRAINS.

Thierry Meylheuc, Christophe Méthivier, Margareth Renault, Jean-Marie Herry, Claire-Marie Pradier, Marie-Noëlle Bellon-Fontaine

The ability of adsorbed biosurfactants (Pf and Lb) obtained from gram negative bacterium (Pseudomonas fluorescens) or gram positive bacterium (Lactobacillus helveticus) to inhibit adhesion of four listerial strains to stainless steel was investigated. These metallic surfaces were characterized…

On the kinetics of CO oxidation by O2 over RhI(CO)2 catalytic species anchored to a zeolitic support

Céline Fontaine-Gautrelet, Cyril Thomas, Jean-Marc Krafft, Gérald Djéga-Mariadassou

The reactivity of RhI(CO)2 towards CO oxidation was studied on a model Rh(0.7 wt%)/HY material. The kinetic results show that RhI(CO)2 exhibit a fairly low activity. It is therefore suggested that the catalytic species responsible for the enhanced activity of Rh/Ce0.68Zr0.32O2 [Manuel et al., J.…
