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…

On Catalytic Behavior of Bulk Mo2C in the Hydrodenitrogenation of Indole over a Wide Range of Conversion Thereof

Marek Lewandowski, Rafał Janus, Mariusz Wądrzyk, Agnieszka Szymańska-Kolasa, Céline Sayag, Gérald Djéga-Mariadassou

The catalytic activity of bulk molybdenum carbide (Mo2C) in the hydrodenitrogenation (HDN) of indole was studied. The catalyst was synthesized using a temperature-programmed reaction of the respective oxide precursor (MoO3) with the carburizing gas mixture of 10 vol.\% CH4/H2. The resultant…

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…

Low Temperature NOx Adsorption Study on Pd-Promoted Zeolites

Alessandro Porta, Tommaso Pellegrinelli, Lidia Castoldi, Roberto Matarrese, Sara Morandi, Stanislaw Dzwigaj, Luca Lietti

In this study Pd-promoted zeolites (BEA, FER, MFI and MOR) are synthesized and investigated for potential use in the low-temperature NOx adsorption. The catalysts are characterized by BET, XRD, UV–Vis and XRF, while the adsorption/desorption characteristics of the samples are investigated by NOx…

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…
