Unlocking synergy in bimetallic catalysts by core–shell design

Jessi van der Hoeven, Jelena Jelic, Liselotte Olthof, Giorgio Totarella, Relinde van Dijk-Moes, Jean-Marc Krafft, Catherine Louis, Felix Studt, Alfons van Blaaderen, Petra de Jongh

Extending the toolbox from mono- to bimetallic catalysts is key in realizing efficient chemical processes1. Traditionally, the performance of bimetallic catalysts featuring one active and one selective metal is optimized by varying the metal composition1,2,3, often resulting in a compromise between…

Preparation, characterization, and hydrogenation activity of new Rh 0 –MCM-41 catalysts prepared from as-synthesized MCM-41 and RhCl 3

Maya Boutros, Georges Moarbess, Thomas Onfroy, Franck Launay

Impregnation of as-synthesized MCM-41 silica by ethanolic solutions of rhodium(III) chloride was tested as an alternative to its introduction into the synthesis gel to get, after calcination and reduction by H2, highly dispersed metal(0) nanoparticles throughout the mesopores network. Rh(III) and…

Improvement of the Catalytic Performances of SBA‐15 in the Formylation of Aniline upon the Introduction of Template‐Free Nano‐Faujasite in Its Synthesis Gel

Karima Baghdad, Mohammed Abdelkrim Hasnaoui, Franck Launay

Faujasite nanoparticles with average size of 10–40 nm were obtained without any organic structure directing agents (Green synthesis), then used as precursors for the synthesis of NaY/SBA-15 composites. Two types of composites were obtained with meso/micro porosity (C1 and C2).The inorganic salt,…

EIS investigations of the oxygen reduction reaction at the cathode of an enzymatic biofuel cell

Achraft Blout, Florence Billon, Hubert Perrot, Claude Jolivalt, Alain Pailleret

Enzymatic biofuel cells (EBCs) have been extensively studied over the last ten years in view of their application as implantable devices [1,2] as they have been shown indeed to reach the power required for small electronic devices. In EBCs, redox reactions occurring at the cathode and the anode are…

Effect of Ca-doping on microstructure and photocatalytic activity of ZnO nanoparticles synthesized by sol gel method

R. Slama, J. El Ghoul, K. Omri, A. Houas, L. El Mir, Franck Launay

We report the synthesis of Zn1−xCaxO nanoparticles prepared by a sol–gel processing technique for x ranging from 0 to 0.05. The structural, morphological and optical properties of the nanoparticles were investigated by X-ray diffraction, transition electron microscopy, UV measurements, and…

Selective gas phase hydrogenation of nitroarenes over Mo 2 C-supported Au-Pd

Xiaodong Wang, Noémie Perret, Laurent Delannoy, Catherine Louis, Mark A. Keane

We report the first synthesis of Mo2C-supported Au and Au–Pd catalysts (nominal Au/Pd = 10 and 30) obtained from colloidal nanoparticles stabilised by polyvinyl alcohol (PVA). Equivalent Au/Al2O3 and Au–Pd/Al2O3 were prepared and served as benchmarks. Residual PVA was removed by thermal treatment…

From 8-hydroxy-5-sulfoquinoline to new related fluorogenic ligands for complexation of aluminium(III) and gallium(III)

Franck Launay, Valérie Alain-Rizzo, Émilie Destandau, Nathalie Ramos, Ēlisabeth Bardez, Paul Baret, Jean-Louis Pierre

The hexadentate tripodal ligand O-TRENSOX (already known as a siderophore), incorporating three 8-hydroxy-5- sulfoquinoline (8-HQS) subunits, was investigated as a potential Ñuorogenic ligand of Al(III) and Ga(III). For the sake of comparison, every chelation study was also carried out with n-BUSOX…
