Development of heterogeneous chemoenzymatic catalysts based on Metal-Organic Framework for the selective and eco-friendly amination of alcohols, Développement de catalyseurs hétérogènes chimioenzymatiques basés sur l'utilisation de polymères de coordination poreux dédiés à l'amination éco-compatible d'alcools

Yifan Zan

The aim of this work was to develop a heterogeneous chemoenzymatic catalyst based on the use of Metal-Organic Frameworks (MOFs) as support for the eco-friendly amination of alcohols in a one-pot cascade synthesis. The cascade process is divided into two steps: an alcohol oxidation chemically…, L'objectif de ce travail était de développer un catalyseur chimio-enzymatique hétérogène basé sur l'utilisation de polymères de coordination poreux (ou Metal-Organic Framework: MOF) comme supports pour l'amination durable d'alcools à travers un procédé en cascade réalisé en une…

Chiral Ammonium-Capped Rhodium(0) Nanocatalysts: Synthesis, Characterization, and Advances in Asymmetric Hydrogenation in Neat Water

Elodie Guyonnet Bil É, Elodie Cortelazzo-Polisini, Audrey Denicourt-Nowicki, Rita Sassine, Franck Launay, Alain Roucoux

Optically active amphiphilic compounds derived from N-methylephedrine, N-methylprolinol, or cinchona derivatives possessing bromide or chiral lactate counterions were efficiently used as protective agents for rhodium(0) nanoparticles. The full characterization of these surfactants and the obtained…

Polyoxotungstates-stabilized gold nanoparticles: how to transfer from an aqueous suspension to CH3CN ?, Nanoparticules d'or stabilisées par des polyoxotungstates : comment passer d'une suspension aqueuse à CH3CN ?

Jean-Baptiste Harlé, Élise Péruse, Jimika Hassanaly, Dalil Brouri, Anna Proust, Audrey Denicourt-Novicky, Alain Roucoux, Anne Gauvin-Bialecki, Richard Villanneau

The present study aims to evaluate available methods for preparing suspensions of gold nanoparticles stabilized by polyoxometalates (POMs@AuNPs) in CH3CN, a solvent commonly used in oxidation reactions. POMs@AuNPs are successfully synthesized in CH3CN using three different approaches: i) in situ…

Design and Analytical Performances of a Diclofenac Biosensor for Water Resources Monitoring

Yacine Mazouzi, Antoine Miche, Alexis Loiseau, Bruno Beito, Christophe Méthivier, Dietmar Knopp, Michèle Salmain, Souhir Boujday

Because the broadly consumed pain killer diclofenac (DCF) is a recognized pollutant, monitoring of its concentration is routinely performed in surface waters. As a valuable alternative to chromatographic and immunochemical assays, we developed a piezoelectric immunosensor to quantify DCF, first in…

Effect of pH on the incorporation of acrylic acid units in the core of polymer nanoparticles prepared by PISA and on their morphology

Clément Debrie, Noémie Coudert, Jean-Michel Guigner, Fanny Coumes, Clément Guibert, Simon Harrisson, François Stoffelbach, Olivier Colombani, Jutta Rieger

Polymerization-induced self-assembly (PISA) is a polymerization process in which amphiphilic block copolymers are simultaneously synthesized and self-assembled in a selective solvent, leading to nanoparticles of different morphologies. Copolymerization has been reported as a means to tune…

Design of Bifunctional Catalysts Based on Bea Zeolites for Tandem Processes with Participation of Ethanol

N. O. Popovych, O. V. Larina, S. M. Orlyk, P. I. Kyriienko, S. O. Soloviev, S. Dzwigaj

The results from the creation of BEA zeolite catalysts, containing heteroelements of Ta(Nb) and modified with d-metals (Ag, Cu, Zn), for processes involving ethanol, are presented. The activity of Ag/BEA in the selective reduction of nitrogen oxides (NOx) with ethanol is due to the presence of…

Characterisation and Reactivity of Oxygen Species at the Surface of Metal Oxides

M. Anpo, Guylène Costentin, E. Giamello, H. Lauron-Pernot, Z. Sojka

Surface reactive oxygen species play a fundamental role in selective oxidation and combustion reactions catalyzed by metal oxides. Unravelling the nature of these transient species, and understanding the details of both their electronic structure and reactivity has been for decades one of the prime…
