Selective Hydrogenation of 1,3-Butadiene in the Presence of an Excess of Alkenes over Supported Bimetallic Gold-Palladium Catalysts

Antoine Hugon, Laurent Delannoy, Jean-Marc Krafft, Catherine Louis

Supported Au catalysts modified by the addition of low amount of Pd (Au/Pd atomic ratio >= 10), prepared by either codeposition-precipitation (DP) or coimpregnation in excess of solution (IES), result in the formation of bimetallic Au Pd particles that promote the selective hydrogenation of…

How Surface Hydroxyls Enhance MgO Reactivity in Basic Catalysis: The Case of Methylbutynol Conversion

Petitjean Hugo, Hazar Guesmi, Lauron-Pernot Hélène, Costentin Guylène, David Loffreda, Philippe Sautet, Françoise Delbecq

This combined experimental and theoretical study aims at understanding why surface hydroxyl groups may enhance catalytic reactivity of MgO surfaces in basic catalysis, whereas hydroxyls are weakly deprotonating groups. We investigated that reactivity enhancement in the catalytic conversion of 2-…

Investigation of ion-selective electrodes with neutral ionophores and ionic sites by EIS. II. Application to K+ detection

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

The impedance of an ion-selective electrode (ISE) to potassium with valinomycin as the ionophore and KBΦ4 as the ionic sites was measured. The membrane was made of PVC with DNP as a plasticizer. The influence of the content of the plasticizer and the membrane thickness was investigated. The…

Control of calcium accessibility over hydroxyapatite by post-precipitation steps: influence on the catalytic reactivity toward alcohols

Manel Ben Osman, Sarah Diallo Garcia, Jean-Marc Krafft, Christophe Methivier, Juliette Blanchard, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Hydroxyapatites are increasingly used as heterogeneous catalysts since they present atypical behaviours for many acid base reactions. The aim of this study was to discuss the possible involvement of Ca2+ Lewis and/or PO–H Brønsted acid sites belonging to the hydroxyapatite system in the conversion…

Discrimination of Surface and Bulk Structure of Crystalline Hydroxyapatite Nanoparticles by NMR

Manel Ben Osman, Sarah Diallo-Garcia, Virginie Herledan, Dalil Brouri, Tetsuya Yoshioka, Jun Kubo, Yannick Millot, Guylène Costentin

Solid state 1H and 31P NMR spectroscopy was used to characterize well-crystallized hydroxyapatite samples of different stoichiometry prepared by a precipitation route. The aim of the paper was to investigate the bulk structural features of samples with different stoichiometry and to discriminate…

Interfacial Coordination Chemistry for Catalyst Preparation

Eric Marceau, Laurent Bonneviot, Stanislaw Dzwigaj, Jean-François Lambert, Catherine Louis, Xavier Carrier

The concept of interfacial coordination chemistry was one of the innovation for which Michel Che became internationally known during his tenure as full professor at the Université Pierre et Marie Curie. Isolated metal ions on oxide surfaces behave like coordination compounds to which the surface…

Framework Stabilization of Ge-Rich Zeolites via Postsynthesis Alumination

Ff Gao, M Jaber, K Bozhilov, A Vicente, Christian Fernandez, V Valtchev

The use of organic structure directing agents in zeolite syntheses has dramatically extended the number of zeolite structure types during the past decades. However, for about 20% of all known zeolite structure types, the necessary postsynthesis elimination of organic templates by high-temperature…
