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…

Cu segregation in Au–Cu nanoparticles exposed to hydrogen atmospheric pressure: how is fcc symmetry maintained?

Q. Wang, A. Nassereddine, D. Loffreda, C. Ricolleau, D. Alloyeau, C. Louis, L. Delannoy, J. Nelayah, H. Guesmi

In a recent work [A. Nassereddine et al., Small 2021, 17, 2104571] we reported the atomic-scale structure and dynamics of sub-4 nm sized Au nanoparticles (NPs) supported on titania in H2 at atmospheric pressure obtained by using aberration-corrected environmental transmission electron microscopy (…

Non-Hydroxyl Radical Species Production during Dark Air Oxidation of Alluvial Soils

Elora Bourbon, Frédéric Averseng, Pierre Le Pape, Thierry Allard, Fulvia Baratelli, Fabrice Alliot, Alexandre Gélabert, Valentine Rollot, Elodie Guigon, Jessica Brest, Sylvie Nélieu, Guillaume Morin

Natural environments subjected to hydrologically-driven redox fluctuations are regarded as propitious to contaminant degradation since they favor cyclic oxygenation of Fe(II)-minerals that produces oxidizing reactive species, such as the hydroxyl radical, OH • . However, the identity of these…

BEA zeolite modified with iron as effective catalyst for N2O decomposition and selective reduction of NO with ammonia

Pawel Boron, Lucjan Chmielarz, J. Gurgul, K. Łątka, Tetsuya Shishido, J.M. Krafft, Stanislaw Dzwigaj

BEA zeolite is modified by a two-steps postsynthesis method allowing incorporate iron atoms into the zeolite framework. Two series of the zeolite samples with aluminium (FexAlSiBEA) and without aluminium (FexSiBEA), containing various iron content (0.5-4.0 Fe wt.%) are obtained. For low Fe content…

Metallic nanoparticles (NPs) have many applications in catalysis. Some of them (gold, silver, copper) have a visible absorption resulting from the excitation of the surface plasmon by an external electromagnetic field. In this project, we propose to couple the catalytic properties of gold-based…, Les nanoparticules (NPs) métalliques ont de nombreuses applications en catalyse. Certaines d’entre elles (or, argent, cuivre) présentent une absorption dans le visible résultant de l’excitation du plasmon de surface par un champ électromagnétique extérieur.
