Influence of Metal Salts Addition on Physical and Electrochemical Properties of Ethyl and Propylammonium Nitrate

David Ausín, José Trenzado, Mireille Turmine, Luis Varela, Oscar Cabeza, Elisa González Romero, Luisa Segade

In this work, we deepen in the characterization of two protic ionic liquids (PILs), ethylammonium nitrate (EAN) and propylammonium nitrate (PAN). With this aim, we determined the influence of inorganic nitrate salts addition on their physical properties and their electrochemical potential window (…

Speciation of Ruthenium as a Reduction Promoter of Silica-Supported Co Catalysts: A Time-Resolved in Situ XAS Investigation

Jingping Hong, Eric Marceau, Andrei Y. Khodakov, Lucia Gaberová, Anne Griboval-Constant, Jean-Sébastien Girardon, Camille La Fontaine, Valérie Briois

Complete reduction of the metal phase in cobalt-containing catalysts is often difficult to reach and can be promoted by a small amount of noble metals. Because these costly promoters are introduced in a very low quantity, their speciation and their chemical interaction with cobalt have seldom been…

Catalytic behavior of copper–amine complex supported on mesoporous silica SBA-15 toward mono-Aza-Michael addition: role of amine groups

Aboubakr Hakiki, Riad Mustpha Kerbadou, Bouhadjar Boukoussa, Hadjira Habib Zahmani, Franck Launay, Alain Pailleret, Françoise Pillier, Salih Hacini, Abdelkader Bengueddach, Rachida Hamacha

This work concerns the preparation and modification of mesoporous silica SBA-15 with different amine-copper complexes in order to study their impact on the catalytic behavior via Aza Michael addition. Firstly, SBA-15 was prepared hydrothermally, then functionalized by mono-, di- and tri-amine, and…

Nouvelles biocathodes graphite/nitrure de carbone amorphe/laccase pour la réduction de l'oxygène par transfert électronique direct

Achraft Blout, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Les enzymes constituent une alternative intéressante aux catalyseurs métalliques car elles possèdent une meilleure sélectivité et des performances catalytiques souvent plus élevées. Elles peuvent être utilisées dans différents types de dispositifs électrochimiques comme les piles à combustible1.…

Cette thèse vise à avancer dans la compréhension de la formation récemment découverte de carbonates amorphes intracellulaires par des cyanobactéries. Des synthèses abiotiques ont permis de produire des carbonates similaires aux inclusions intracellulaires en termes de morphologie, structure et…, In this thesis we study the recently discovered formation of intracellular amorphous carbonates by cyanobacteria. Abiotic syntheses produced carbonates with a morphology, structure and composition similar as intracellular inclusions. The intracellular chemical conditions in the cyanobacteria can be…
