The influence of C1 and C2 organic reducing agents on catalytic properties of Co(II)-single site BEA zeolite in SCR of NO

Janusz Janas, Wojciech Rojek, Stanislaw Dzwigaj

CoSiBEA zeolite with 0.9 wt.% Co is prepared in acidic (pH = 2.5) condition by a two-step postsynthesis method which allows to incorporate cobalt into framework zeolite as isolated tetrahedral Co(II) species, as evidenced by XRD and diffuse reflectance UV-vis. As obtained Co(II)-single site zeolite…

Chromium sites in zeolite framework: Chromyl or chromium hydroxyl groups?

Frederik Tielens, Mazharul M. Islam, Gabriella Skara, F. de Proft, Tetsuya Shishido, Stanislaw Dzwigaj

A combined experimental and ab initio periodic DFT calculation on the structure and stability of different chromium-substituted zeolite models are presented. Experimental investigation by XRD, FT-IR and UV-vis show the presence of chromium in SiBEA zeolite. The favorable chromium sites are…

Influence of the preparation procedure on the nature and environment of vanadium in VSiBEA zeolite: XRD, DR UV-vis, NMR, EPR and TPR studies

Rafal Baran, Yannick Millot, Thomas Onfroy, Frédéric Averseng, Jean-Marc Krafft, Stanislaw Dzwigaj

Two series of VxSiBEA(I) and VxSiBEA(II) zeolites have been prepared by a two-steps postsynthesis method which consists, in the first step, in the dealumination of TEABEA zeolite by two different procedures to obtain SiBEA(I) and SiBEA(II) zeolites and then, in the second step, in contacting the…

Silver species reduction upon exposure of Ag/Al2O3 catalyst to gaseous ethanol: An in situ Quick-XANES study

Elie Sayah, Camille La Fontaine, Valérie Briois, Dalil Brouri, Pascale Massiani

The evolution of supported silver species of a pre-calcined Ag/Al2O3 catalyst was monitored upon thermal treatment under an air flow enriched with 3000 ppm of ethanol (EtOH) using transmission electron microscopy and UV-visible and X-ray absorption spectroscopies. A special focus is put on the…

Specificinteractions of functionalisedgoldsurfaces with ammonium perchlorate or starch; towards a chemical cartography of their mixture

D. Mercier, C. Mercader, S. Quere, Lionel Hairault, Christophe Methivier, Claire-Marie Pradier

By functionalising gold samples, planar wafers or AFM tips, with an acid- or an amino acid-terminated thiols, mercaptoundecanoic acid (MUA) and homocystein (H-Cyst) respectively, we were able to differentiate the interactions with ammonium perchlorate (AP) and starch (S), two components of a…

Combined fungal and chemical pretreatment of lignocellulosic biomass for biogas production enhancement: effect of pretreatment order and fungal strains

Shruthi Meenakshisundaram, Vincenzo Calcagno, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Xiaojun Liu, Claude Jolivalt, André Pauss

Combining fungal and chemical pretreatment has been shown to reduce the drawbacks of sole pretreatment while improving biofuel yields. White rot fungi are well known for their unique oxidative enzyme system which is capable of mineralizing lignin. However, their uncertainty of performance and long…
