Nature of the active sites in CO oxidation on FeSiBEA zeolites

Ireneusz Kocemba, Jacek Rynkowski, Jacek Gurgul, Robert P. Socha, Kazimierz Łątka, Jean-Marc Krafft, Stanislaw Dzwigaj

FeSiBEA zeolites containing 1 wt% of iron were prepared by a two-step postsynthesis method in acidic (pH = 2.6) (Fe1.0SiBEA(w)) and alkaline (pH = 10) (Fe1.0SiBEA(p)) conditions. The structure of the studied materials, their acidity as well as the nature and environment of iron present in the…

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…

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…

Mononuclear pseudo-tetrahedral V species of VSiBEA zeolite as the active sites of the selective oxidative dehydrogenation of propane

Karolina Chalupka, Cyril Thomas, Yannick Millot, Frédéric Averseng, Stanislaw Dzwigaj

This work reports on the investigation of the influence of the nature of the V species in the ODH of propane. For this purpose, VSiBEA catalysts, including framework and/or extra-framework V species, were synthesized via the two-step method by controlling the speciation of the V species of the…

BSA and lysozyme adsorption on homoionic montmorillonite: Influence of the interlayer cation

Mathilde Lepoitevin, Maguy Jaber, Régis Guégan, Jean-Marc Janot, Philippe Dejardin, Francois Henn, Sébastien Balme

This study aims to investigate the influence of interlayer cation alkali metal series (Li+, Na+, K+, Rb+, Cs+) and alkali earth metal (Mg2 +, Ca2 +, Ba2 +) on adsorption of model proteins (lysozyme and bovine serum albumin). The localizations of both proteins and their conformational modifications…

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…
