In situ observation of atomic redistribution in alloying gold-silver nanorods

Jessi E S van Der Hoeven, Tom a J Welling, Tiago a G da Silva, Jeroen E van den Reijen, Camille La Fontaine, Xavier Carrier, Catherine Louis, Alfons van Blaaderen, Petra E de Jongh

The catalytic performance and optical properties of bimetallic nanoparticles critically depend on the atomic distribution of the two metals in the nanoparticles. However, at elevated temperatures, during light induced heating or during catalysis atomic redistribution can occur. Measuring such metal…

Assessing carbon or tungstates coverage of ZrO2 nanoparticles supported on MWCNT via NOx-TPD

Patrick Kelleher, Gary Haller, Sandra Casale, Christophe Méthivier, Cyril Thomas

Multi-walled carbon nanotubes (MWCNT) promoted by oxides, that are far from trivial to characterize, have emerged as promising candidates in several fields such as biosensors and catalysis. In this study the coverage of ZrO2 nanoparticles supported on MWCNT, by carbonaceous deposits or tungstates…

Elucidation of the IR of Cu and Mn substituted intraframework SiBEA zeolites

Etienne Hessou, Michael Badawi, Laetitia Valentin, Guy Atohoun, Stanislaw Dzwigaj, Monica Calatayud, Frederik Tielens

Copper and manganese modified zeolites play key roles in selective oxidation catalytic reactions. Combining Density Functional Perturbation Theory (DFPT) implemented in VASP, and infrared spectroscopy experiments, we have studied and elucidated the incorporation of Cu 2+ and Mn 2+ in the framework…

Silk bionanocomposites : design, characterization and potential applications, Bionanocomposites à base de soie : élaboration, caractérisation et applications potentielles

Cristina Belda Marín

Silk-based bionancompoistes have attracted a growing interest in numerous applications, particularly in the biomedical field, owing to their ability to combine the specific properties of silk fibroin (biodegradability, biocompatibility and interesting mechanical properties) and nanoparticles (NPs…, Les « bionanocomposites » à base de soie sont des matériaux qui suscitent un intérêt croissant dans de nombreuses applications, et en particulier dans le domaine biomédical, de par leur capacité à combiner les propriétés de la fibroïne (biodégradabilité, biocompatibilité et propriétés mécaniques…

Aerobic oxidation of alcohols using ruthenium supported on DD3 kaolin

B. Zadam, D. Obaid, A. Mayoufi, P. Beaunier, F. Launay, F. El Berrichi

Supported ruthenium nanoparticles were prepared through the chemical reduction of aqueous Ru(III) species previously loaded (1 or 5 wt%) onto DD3 kaolin through an ion-exchanged pathway. Resulting nanoporous materials were characterized by XRF, XRD, TEM, EDX, and N2 sorption measurements, and then…
