Influence of the texturalproperties of porousaluminas on the reducibility of Ni/Al2O3 catalysts

Faiza Bentaleb, Eric Marceau

Temperature-programmed reduction (TPR) profiles recorded on calcined Ni/Al2O3 catalysts exhibiting the same Ni(II) surface density (3 Ni2+ nm−2) suggest that nickel speciation and reducibility are significantly influenced by the specific surface area and texturalproperties of aluminas, and by their…

Halide-free CO 2 cycloaddition onto styrene oxide catalysed by first row transition-metal derivatives of polyoxotungstates

Jingjing Ren, Franck Launay, Richard Villanneau, Anna Proust

Quaternary ammonium salts of metal derivatives of polyoxometalates [XW11O39M(H2O)]n- (X = P, Si; M = Cr, Mn, Co, Ni, Zn) were successfully tested instead of quaternary ammonium halides as catalysts in the cycloaddition of CO2 to styrene oxide. Remarkably, they gave very satisfactory yields of…

Coupled quartz crystal microbalance – Surface enhanced Raman scattering strategy for the design and testing of aptasensors for small analytes

Médéric Lequeux, Michèle Salmain, Jean-Marc Krafft, Jakub Dostalek, Anne Vallée, Alexis Loiseau, Wolfgang Knoll, Marc Lamy de la Chapelle, Souhir Boujday

Both quartz crystal microbalance with dissipation (QCM-D) and Surface Enhanced Raman Scattering (SERS) stand at the forefront of label-free transducing techniques to trace and monitor biomolecular association events occurring at solid-liquid interfaces. Although these techniques provide highly…

Molten Salts‐Driven Discovery of a Polar Mixed‐Anion 3D framework at the nanoscale: Zn4Si2O7Cl2, Charge Transport and Photoelectrocatalytic Water Splitting

Ram Kumar, Yang Song, Anissa Ghoridi, Philippe Boullay, Gwenaelle Rousse, Christel Gervais, Cristina Coelho Diogo, Houria Kabbour, Capucine Sassoye, Patricia Beaunier, Victor Castaing, Bruno Viana, Maria Luisa Ruiz Gonzalez, José Gonzalez Calbet, Christel Laberty-Robert, David Portehault

Mixed-anion compounds widen the chemical space of attainable materials compared to single anionic compounds, but the exploration of their structural diversity is limited by common synthetic paths. Especially, oxychlorides rely mainly on layered structures, which suffer from low stability during…

Loop-stabilized BAB triblock copolymer morphologies by PISA in water

Pauline Biais, Patricia Beaunier, François Stoffelbach, Jutta Rieger

A straightforward strategy to synthesize in water, loop-stabilized particles via PISA is developed. These particular structures can in theory be obtained through the synthesis of amphiphilic BAB triblock copolymers, starting from a hydrophilic middle block A, which is chain extended in an aqueous…

Advantages of Covalent Immobilization of Metal‐Salophen on Amino‐Functionalized Mesoporous Silica in Terms of Recycling and Catalytic Activity for CO 2 Cycloaddition onto Epoxides

Matthieu Balas, Sébastien Beaudoin, Anna Proust, Franck Launay, Richard Villanneau

NiII and MnIII Schiff base complexes (Salophen-Ni and Salophen-MnCl) bearing a pending carboxylic group were prepared and characterized. Both complexes were grafted onto a mesoporous amino-functionalized SBA-15 silica, by formation of an amide function between the propylamine groups of the support…
