Characterisation and Reactivity of Oxygen Species at the Surface of Metal Oxides

M. Anpo, Guylène Costentin, E. Giamello, H. Lauron-Pernot, Z. Sojka

Surface reactive oxygen species play a fundamental role in selective oxidation and combustion reactions catalyzed by metal oxides. Unravelling the nature of these transient species, and understanding the details of both their electronic structure and reactivity has been for decades one of the prime…

Cobalt-containing BEA zeolite for catalytic combustion of toluene

Anna Rokicińska, Marek Drozdek, Barbara Dudek, Barbara Gil, Piotr Michorczyk, Dalil Brouri, Stanislaw Dzwigaj, Piotr Kuśtrowski

Co-containing HAlBEA zeolite was obtained by conventional wet impregnation of HAlBEA zeolite with an aqueous Co(NO3)2.6 H2O solution, whereas Co-containing SiBEA zeolites were prepared by a two-step post-synthesis method. This approach consists of, in the first step, dealumination of parent BEA…

Experimental evidence of NO SCR mechanism in the presence of the BEA zeolite with framework and extra-framework cobalt species

Paweł Boroń, Lucjan Chmielarz, Barbara Gil, Bartosz Marszałek, Stanislaw Dzwigaj

Temperature-programmed desorption (TPD), temperature-programmed surface reaction (TPSR) and stop flow-TPD techniques as well as FT-IR spectroscopy of pre-adsorbed NH3 and NO are applied to characterize active sites present in Co-containing BEA zeolites. Cobalt is introduced into BEA zeolite by…

Heterostructured Cobalt Silicide Nanocrystals: Synthesis in Molten Salts, Ferromagnetism, and Electrocatalysis

Yang Song, Isabel Gómez-Recio, Anissa Ghoridi, Fernando Igoa Saldaña, Daniel Janisch, Capucine Sassoye, Vincent Dupuis, David Hrabovsky, M. Luisa Ruiz-González, José González-Calbet, Sandra Casale, Andrea Zitolo, Benedikt Lassalle-Kaiser, Christel Laberty-Robert, David Portehault

Nanoscale heterostructures of covalent intermetallics should give birth to a wide range of interface-driven physical and chemical properties. Such a level of design however remains unattainable for most of these compounds, due to the difficulty to reach a crystalline order of covalent bonds at the…

Metal–Support Interactions in Pt-WO 3 Heterostructures: Role of WO 3 Polymorphism

Isabel Gómez-Recio, Cyril Thomas, Christophe Méthivier, María Luisa Ruiz-González, José González-Calbet, David Portehault

Ionic exchange under soft conditions yields nanoplatelets of tungsten bronzes with an original crystal structure doped with cobalt, copper, platinum, and cesium cations (h′-MxWO3). The optimal orientation of the tunnel-based crystal structure, perpendicular to the basal plane of the nanoplatelets,…

Phosphorylation of a conserved serine in the deoxyribonucleic acid binding domain of nuclear receptors alters intracellular localization.

Kai Sun, Vedrana Montana, Karthikeyani Chellappa, Yann Brelivet, Dino Moras, Yutaka Maeda, Vladimir Parpura, Bryce M Paschal, Frances M Sladek

Nuclear receptors (NRs) are a superfamily of transcription factors whose genomic functions are known to be activated by lipophilic ligands, but little is known about how to deactivate them or how to turn on their nongenomic functions. One obvious mechanism is to alter the nuclear localization of…

Gold Nanoparticles on Oxide-Free Silicon-Molecule Interface for Single Electron Transport

Louis Caillard, Oliver Seitz, Philip M. Campbell, Rachel P. Doherty, Anne-Félicie Lamic-Humblot, Emmanuelle Lacaze, Yves J. Chabal, Olivier Pluchery

Two different organic monolayers were prepared on silicon Si(111) and modified for attaching gold nanoparticles. The molecules are covalently bound to silicon and form very ordered monolayers sometimes improperly called self-assembled monolayers (SAM). They are designed to be electrically…
