Cobalt-containing BEA zeolite for catalytic combustion of toluene

Anna Rokicińska, Marek Drozdek, Barbara Dudek, Barbara Gil, Piotr Michorczyk, Dalil Brouri, Stanislaw Dzwigaj, Piotr Kuśtrowski

Co-containing HAlBEA zeolite was obtained by conventional wet impregnation of HAlBEA zeolite with an aqueous Co(NO3)2.6 H2O solution, whereas Co-containing SiBEA zeolites were prepared by a two-step post-synthesis method. This approach consists of, in the first step, dealumination of parent BEA…

Investigation of the plate-impact method as a precursor of physical phenomena and chemical processes, L'étude de la méthode de l'impact par plaque comme précurseur des phénomènes physiques et des processus chimiques

Maya Mounir Daou

This manuscript aims at characterizing a new device based on a plate impact on a liquid surface to generate cavitation and evaluate its potential to induce chemical reactions. The device is composed of a reactor containing a liquid that a piston hits due to pressure difference. This impact…, Ce manuscrit a pour but d'étudier un nouveau dispositif générateur de cavitation dont le potentiel favorable à l'intensification de réactions chimiques est évalué. Ce dispositif est constitué d'une plaque mobile qui frappe un liquide contenu dans un réacteur. L'impact génère une…

Experimental evidence of NO SCR mechanism in the presence of the BEA zeolite with framework and extra-framework cobalt species

Paweł Boroń, Lucjan Chmielarz, Barbara Gil, Bartosz Marszałek, Stanislaw Dzwigaj

Temperature-programmed desorption (TPD), temperature-programmed surface reaction (TPSR) and stop flow-TPD techniques as well as FT-IR spectroscopy of pre-adsorbed NH3 and NO are applied to characterize active sites present in Co-containing BEA zeolites. Cobalt is introduced into BEA zeolite by…

Platinum-zeolite hybrid catalyst for the electrooxidation of formic acid

Lu Zhang, Juan V Perales-Rondón, Angélica Thomère, Juliette Blanchard, Carlos M Sánchez-Sánchez

Formic acid oxidation reaction (FAOR) was studied using different platinum-zeolites hybrid catalysts. The catalysts were prepared by addition of two different forms of the ZSM-5 zeolite (ZSM-5-H+ and ZSM-5-NH4+) to an ink containing Vulcan carbon support and Pt nanoparticles (NPs). TEM images…

Atomic Scale Observation of the Structural Dynamics of Supported Gold Nanocatalysts under 1,3‐Butadiene by in situ Environmental Transmission Electron Microscopy

Abdallah Nassereddine, Laurent Delannoy, Christian Ricolleau, Catherine Louis, Alloyeau D., Guillaume Wang, Qing Wang, Hazar Guesmi, Jaysen Nelayah

Supported gold catalysts have been reported to exhibit exceptional selectivity towards the desirable product, an alkene, in chemoselective hydrogenation of highly unsaturated alkynes and alkadienes. However, insights on the interactions between the gold nanoparticles and the 1,3‐butadiene…
