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…

Photoelectrochemical properties of ZnS- and CdS-TiO 2 nanostructured photocatalysts: Aqueous sulfidation as a smart route to improve catalyst stability

Samiha Chaguetmi, Larissa Chaperman, Sophie Nowak, Delphine Schaming, Stephanie Lau-Truong, Philippe Decorse, Patricia Beaunier, Cyrille Costentin, Fayna Mammeri, Slimane Achour, Souad Ammar

ZnS- and CdS-TiO2 hetero-nanostructures were synthesized by impregnation of polyol-made ZnS, CdS quantum dots (QDs) on the surface of TiO2 nanofibers that were grown on Ti sheets by controlled corrosion. Due to their finite size, the grafted QDs were partly oxidized, when air exposed, reducing…

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…
