Mechanistic Investigation of Isopropanol Conversion on Alumina Catalysts: Location of Active Sites for Alkene/Ether Production

Kim Larmier, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Johnny Abboud, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Alcohol dehydration is of prominent relevance in the context of biomass conversion. This reaction can be efficiently catalyzed by alumina surfaces, but the nature of active sites, the mechanisms involved, and the key parameters to tune both the activity and the alkene/ether selectivity remain a…

Characterizing a supported catalyst : a methodological approach

Eric Marceau

The characterization of supported catalysts requires the combination of several physicochemical and spectroscopic techniques in order to investigate the support and active phase composition, morphology and reactivity. The most common techniques used at the laboratory are detailed in this chapter…

High selectivity of TaSiBEA zeolite catalysts in 1,3-butadiene production from ethanol and acetaldehyde mixture

Pavlo I. Kyriienko, Olga V. Larina, Sergiy O. Soloviev, Svitlana M. Orlyk, Stanislaw Dzwigaj

New tantalum-silica based zeolite catalysts (TaSiBEA) were applied in this work for 1,3-butadiene production from ethanol. Tantalum incorporation into vacant T-atom sites of the SiBEA zeolites framework as mononuclear Ta(V) allowed preparing highly selective catalysts for ethanol/acetaldehyde…

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…
