Pd–Cu Alloy Nanoparticles Confined within Mesoporous Hollow Carbon Spheres for the Hydrogenation of CO 2 to Formate

Guoxiang Yang, Yasutaka Kuwahara, Kohsuke Mori, Catherine Louis, Hiromi Yamashita

It is intriguing yet challenging to synthesize high-performance heterogeneous catalysts for carbon dioxide (CO2) hydrogenation reactions. The excellent catalytic performance of heterogeneous catalysts has attracted widespread attention recently. Herein, a series of Pd–Cu alloy nanoparticles…

Identification of cationic and oxidic caesium species in basic Cs-overloaded BEA zeolites

Pascale Massiani, C. Bisio, Katia Fajerwerg, L. Sordelli, L. Stievano, E.R. Silva, S. Coluccia, G. Martra

A parent acidic H-BEA with crystallites very small in size and high external surface area was used to prepare a series of materials loaded with increasing Cs+ contents by firstly ion-exchange and then impregnation with CsOH solutions. The monitoring of the ion- exchange process by chemical analysis…

EXAFS spectroscopy as a tool to probe metal–support interaction and surface molecular structures in oxide-supported catalysts: application to Al2O3-supported Ni(ii) complexes and ZrO2-supported tungstates

Xavier Carrier, Eric Marceau, Hugo Carabineiro, Vicente Rodríguez-González, Michel Che

EXAFS spectroscopy is shown as a tool of prime importance to probe the formation of metal–oxygen–support bonds and unravel the surface molecular structure in oxide-supported systems through two examples: (i) a molecular metal complex (Ni(II) bisglycinate) characterized after impregnation and drying…

Gold nanoparticle-based localized surface plasmon immunosensor for staphylococcal enterotoxin A (SEA) detection

Maroua Ben Haddada, David Hu, Michèle Salmain, Lu Zhang, Chen Peng, Yi Wang, Bo Liedberg, Souhir Boujday

We describe the engineering of stable gold nanoparticle (AuNP) bioconjugates for the detection of staphylococcal enterotoxin A (SEA) using localized surface plasmon resonance (LSPR). Two types of AuNP bioconjugates were prepared by covalently attaching anti-SEA antibody (Ab) or SEA to AuNPs. This…

Understanding of the oxygen activation on ceriaand ceria/alumina-supported gold catalysts: a study combining 18O/16O isotopic exchange and EPR spectroscopy

Pandian Lakshmanan, Frédéric Averseng, Nicolas Bion, Laurent Delannoy, Jean-Michel Tatibouet, Catherine Louis

Gold supported on ceria or ceria-alumina mixed oxides are very active catalysts for total oxidation of a variety of molecules. The key step of the oxygen activation on such catalysts is still a matter of debate. Gold-ceria (Au/CeO2) and gold-ceria-alumina (Au/CeO2/Al2O3) catalysts were prepared by…

DFT study of the M segregation on MAu alloys (M = Ni, Pd, Pt) in presence of adsorbed oxygen O and O2

Adnene Dhouib, Hazar Guesmi

Segregation phenomena of group 10 (M = Ni, Pd, Pt) transition-metals substituted in Au (1 1 1) surface and sub-surface layers are investigated by DFT periodic calculations in presence of adsorbed atomic and molecular oxygen. In contrast with vacuum conditions, where the metal impurities M prefer to…

Unravelling the enhanced reactivity of bulk CeO2 doped with gallium: A periodic DFT study

Paola Quaino, Olga Syzgantseva, Luca Siffert, Frederik Tielens, Christian Minot, Monica Calatayud

Doping CeO2 with gallium leads to promising materials with application in hydrogen purification processes for fuel cells. The bulk ceria-gallia is investigated by ab initio calculations. The outstanding reactivity is explained by important relaxations induced by gallium in the ceria host, having a…
