Ordered mesoporous “one-pot” synthesized Ni-Mg(Ca)-Al2O3 as effective and remarkably stable catalysts for combined steam and dry reforming of methane (CSDRM)

Karam Jabbour, Pascale Massiani, Anne Davidson, Sandra Casale, Nissrine El Hassan

Two series of Nix% (x: 5–10 wt%) and Ni5%M5% (M: Ca or Mg) containing mesoporous Al2O3 catalysts were prepared by “one-pot” synthesis following an evaporation-induced self-assembly (EISA) method. After reduction, the catalysts showed very high Ni dispersion within the structured oxide matrix giving…

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…

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…

Remarkable effect of postsynthesis preparation procedures on catalytic properties of Ni-loaded BEA zeolites in hydrodechlorination of 1,2-dichloroethane

A. Śrębowata, R. Baran, D. Łomot, D. Lisovytskiy, T. Onfroy, S. Dzwigaj

Ni2.0SiBEA and Ni2.0HAlBEA zeolites were prepared by two different procedures: (i) a two-step postsynthesis method that consist of (1) creation of vacant T-atom sites by dealumination of HAlBEA (Si/Al = 17) with nitric acid and then (2) impregnation of as resulting SiBEA (Si/Al > 1300) with…

Design and Analytical Performances of a Diclofenac Biosensor for Water Resources Monitoring

Yacine Mazouzi, Antoine Miche, Alexis Loiseau, Bruno Beito, Christophe Méthivier, Dietmar Knopp, Michèle Salmain, Souhir Boujday

Because the broadly consumed pain killer diclofenac (DCF) is a recognized pollutant, monitoring of its concentration is routinely performed in surface waters. As a valuable alternative to chromatographic and immunochemical assays, we developed a piezoelectric immunosensor to quantify DCF, first in…

Biosensing Extracellular Vesicle Subpopulations in Neurodegenerative Disease Conditions

Yacine Mazouzi, Fadoua Sallem, Francesca Farina, Alexis Loiseau, Natayme Rocha Tartaglia, Morgane Fontaine, Atul Parikh, Michèle Salmain, Christian Neri, Souhir Boujday

Extracellular vesicles (EVs) are secreted nanoparticles that are involved in intercellular communication and that modulate a wide range of biological processes in normal and disease conditions. However, EVs are highly heterogeneous in terms of origin in the cell, size, and density. As a result,…
