Conception raisonnée de catalyseurs bifonctionnels : élaboration de catalyseurs Pt0/zéolithe-Alumine, Rational design of bifunctional catalysts : development of Pt0/zeolithe-alumina catalysts

Olfa Ben Moussa

Les catalyseurs bifonctionnels pour l’hydrocraquage nécessitent à la fois des sites acides de Brønsted et des sites métalliques. L’intimité entre sites acides et sites métalliques peut donc influer sur l’activité et la sélectivité de la réaction. Nous nous sommes proposés d’explorer l’effet de la…, Bifunctional hydrocracking catalysts require both Brønsted acid sites and metal sites. Hence, the intimacy between acid sites and metal sites can influence the activity and selectivity of the reaction. We intended to explore the effect of metal sites-acid sites distance on the conversion of n-…

Enhancement of water remediation by innovative photocatalytic luminous textiles reactor: Performance, kinetic modeling, and mechanistic insights

Sarra Karoui, Aymen Amine Assadi, Achraf Ghorbal, Lotfi Khezami, Achraf Assadi, Sivachandiran Loganathan, Abdeltif Amrane

To address wastewater treatment, a photocatalytic process using luminous-textile has been proposed due to its high efficiency and non-toxicity. In the present work, the photodegradation of Ciprofloxacin (CIP) in the liquid phase was studied in a compact reactor with a luminous-textile catalyst in…

Synthèse et fonctionnalisation de nanobâtonnets d’or enrobés de silice AuNR@SiO2 pour des applications aux biointerfaces, Synthesis and functionalization of silica coated gold nanorod AuNR@SiO2 for biointerfaces applications

Vincent Pellas

Les nanobâtonnets d’or sont des particules plasmoniques présentant des propriétés optiques intéressantes. En particulier, la résonance plasmonique de surface localisée (LSPR) sensible à l’environnement local des particules, permet leur utilisation comme transducteurs de phénomènes d’interactions…, Gold nanorods are plasmonic nanoparticles with interesting optical properties. In particular, the localized surface plasmon resonance (LSPR), sensitive to the local environment of the particles, allows their use as transducers of molecular interaction phenomena. This property makes those…

La Recherche en Chimie aux Frontières de la Connaissance

Dominique Massiot, Claire-Marie Pradier, Jacques Maddaluno, Jean-François Tassin, Joël Moreau, Mehran Mostafavi, Anne Imberty, Pascal Breuilles, Catherine Larroche

L’Unité Mixte de Recherche est la brique élémentaire, souple et pérenne d’un paysage de la recherche en évolution rapide. De nombreux dispositifs viennent structurer l’activité de ces équipes pour faire émerger des pôles de recherche, consolider le maillage des réseaux nationaux, identifier les…, Mixed research units are building blocks, flexible but permanent, in rapidly evolving fields of research. Several measures shape the activities of research teams and thus give rise to “poles of research”. They also help consolidate national networks, identify strong points, boost the sharing of top…

Assessing the Oxidation Behavior of EC:DMC Based Electrolyte on Non- Catalytically Active Surface

Iban Azcarate, Wei Yin, Christophe Méthivier, François Ribot, Christel Laberty-Robert, Alexis Grimaud

The race for developing Li-ion batteries positive electrodes with always greater energy density has recently renewed interest towards understanding the formation of the so-called cathode electrolyte interface (CEI) forming upon cycling at high potential. In this work, we used an approach combining…

Polyol Process Coupled to Cold Plasma as a New and Efficient Nanohydride Processing Method: Nano-Ni 2 H as a Case Study

Sonia Haj-Khlifa, Sophie Nowak, Patricia Beaunier, Patricia de Rango, Michaël Redolfi, Souad Ammar-Merah

An alternative route for metal hydrogenation has been investigated: cold plasma hydrogen implantation on polyol-made transition metal nanoparticles. This treatment applied to a challenging system, Ni-H, induces a reordering of the metal lattice, and superstructure lines have been observed by both…

Influence of the Ageing and Drying Steps of a CoMoP/γ‐Al2O3 Catalyst onto the Multi‐Scale Molybdenum Active Phase Organization

Candice Cottrez, Séverine Humbert, Anne‐sophie Gay, Elodie Devers, Frédéric de Geuser, Xavier Carrier, Alexandra Chaumonnot

To study the influence of ageing and drying steps onto the multiscale Mo active phase arrangement (i. e. MoS2 slabs and slab aggregates), a series of highly loaded CoMoP/γ-Al2O3 catalysts aged, unaged, dried or freeze-dried were prepared and tested in toluene hydrogenation. Electron Probe Micro…

Operando X‐ray Absorption Study of TiO₂‐supported Au, Cu, and Au–Cu Catalysts for Butadiene Selective Hydrogenation

Abdallah Nassereddine, Laurent Delannoy, Xavier Carrier, Catherine Louis, Camille La Fontaine, Anthony Beauvois, Jaysen Nelayah, Axel Wilson

The selective hydrogenation of unsaturated hydrocarbons is essential for the production of alkenes used in polymerization processes. Au‐based catalysts offer greater selectivity than Pd but are limited by poor hydrogen activation. Alloying Au with Cu offers a promising approach to enhance catalytic…
