Kinetic Model of Energy Transfer Processes Between Low-Coordinated Ions on MgO by Photoluminescence Decay Measurements

Céline Chizallet, Guylène Costentin, Jean-Marc Krafft, Hélène Pernot, Michel Che

Photoluminescence decay studies of emitting species on MgO nanocubes at room temperature provide evidence of three sur- face species characterized by an excitation and emission wave- length couple {l exc ;l em }.Species A corresponds to {l exc =240 nm; l em =380 nm},whereas the couple {l exc =280…

ZnO oxygen vacancies formation and filling followed by in situ photoluminescence and in situ EPR

C. Drouilly, J.M. Krafft, F. Averseng, S. Casale, Delphine Bazer-Bachi, Céline Chizallet, V. Lecocq, H. Vezin, H. Lauron-Pernot, G. Costentin

Oxygen vacancies of zinc oxide were followed by photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopies. The green PL emission was associated with oxygen vacancies: its intensity is enhanced upon static thermal treatment under inert or under vacuum, whereas it decreases upon…

Identification of Surface Basic Sites and Acid–Base Pairs of Hydroxyapatite

Sarah Diallo-Garcia, Manel Ben Osman, Jean-Marc Krafft, Sandra Casale, Cyril Thomas, Jun Kubo, Guylène Costentin

The Lewis and Brønsted basic properties of a stoichiometric hydroxyapatite (HAp) were investigated by infrared spectroscopy following the adsorption and desorption processes of a Lewis acidic molecule, CO2, and a Brønsted acidic molecule, C2H2. CO2 interacts with basic OH– and O2– of PO43– groups…

Fluidized bed plasmas reactor for catalyst synthesis and pretreatment. Application for pollution abatement in stationary and mobile sources

Marjorie Foix, Cedric Guyon, Michael Tatoulian, Patrick da Costa

The prepn. of automotive catalysts and com. oxidn. catalysts in stationary sources use a large amt. of noble metal precursors. Moreover, during their prepn. high energy (gas and temp.) is necessary for treatment processes. In order to develop a higher sustainable process, the plasma-assisted…

Catalytic properties of AgAlBEA and AgSiBEA zeolites in H2-promoted selective reduction of NO with ethanol

Nataliia Popovych, Pavlo Kyriienko, Sergiy Soloviev, Svitlana Orlyk, Stanislaw Dzwigaj

Physicochemical properties of AgAlBEA and AgSiBEA zeolites were investigated by IR spectroscopy with pyridine, H2-TPR, XPS and diffuse reflectance UV–vis spectroscopy. Their catalytic properties were studied in the process of selective reduction of NO with ethanol and in the presence of hydrogen in…
