Effect of water on cobalt speciation during solid-state synthesis of Co2+/ZSM5 catalysts: quantitative study by TPR and XAS

Eric Marceau, Michel Che, Françoise Villain, Younès Ben Taarit

The effect of water on cobalt speciation in the synthesis of Co2+/ZSM5 catalysts is quantitatively studied by the combined use of macroscopic and local characterization techniques, TPR and X-ray absorption spectroscopies, respectively. The addition of a small quantity of water to cobalt acetate and…

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…

Control of the anisotropic shape of cobalt nanorods in the liquid phase: from experiment to theory… and back

Kahina Aït Atmane, Carine Michel, Jean-Yves Piquemal, Philippe Sautet, Patricia Beaunier, Marion Giraud, Mickaël Sicard, Sophie Nowak, Rémi Losno, G. Viau

The polyol process is one of the few methods allowing the preparation of metal nanoparticles in solution. Hexagonal close packed monocrystalline Co nanorods are easily obtained in basic 1,2-butanediol at 448 K after a few minutes using a Co(II) dicarboxylate precursor. By using a combined…

Gensdarmes, G. Dinescu, T. Acsente, C. Uboldi, T. Orsiere, Veronique Malard, B. Rousseau, G. Dine, Ph. Delaporte, C Grisolia

During ITER operation, it is expected that the large panel of plasma-wall interactions triggers the production of dust particles from the tungsten and beryllium first wall. These particles can be loaded with tritium (T) used as a fuel for the fusion reaction; T inventory is of prime importance for…

Insight into the Nature of the ZnO x Promoter during Methanol Synthesis

Remco Dalebout, Laura Barberis, Giorgio Totarella, Savannah Turner, Camille La Fontaine, Frank de Groot, Xavier Carrier, Ad van der Eerden, Florian Meirer, Petra de Jongh

Despite the great commercial relevance of zinc-promoted copper catalysts for methanol synthesis, the nature of the Cu–ZnOx synergy and the nature of the active Zn-based promoter species under industrially relevant conditions are still a topic of vivid debate. Detailed characterization of the…

On the influence of water traces on the acidity measurement of amorphous aluminosilicates

Juliette Blanchard, Jean-Marc Krafft, Colin Dupont, Céline Sayag, Toshikazu Takahashi, Hiroyuki Yasuda

For the measurement of their acidity, amorphous aluminosilicates are beforehand treated at temperature of 450 • C or higher in order to remove water adsorbed on their surface. We will show in this study that, during the standard course of an acidity measurement by low temperature CO adsorption,…

Redox-Triggered Control of Cell Adhesion and Deadhesion on Poly(lysine)- g -poly(ethylene oxide) Adlayers

Louise Hespel, Julien Dupré de Baubigny, Pierre Lalanne, Simon de Beco, Mathieu Coppey, Catherine Villard, Vincent Humblot, Emmanuelle Marie, Christophe Tribet

Spontaneous adsorption of poly(lysine)-g-poly(ethyleneglycol) comb-like copolymers (PLL-g-PEG) is a versatile mean to coat substrates with polymer layers that resist cell adhesion. We prepared redox cleavable PLL-g-PEG to switch adhesion on demand. Redox sensitivity was obtained by introducing…
