Role of active components of an Ag/Al2O3/cordierite catalyst in selective reduction of NO by ethanol

N. A. Popovich, P. I. Kiriienko, S. Solov’ev, S. Orlik, S. Dzwigaj

We show that the activity of silver/aluminum oxide catalysts in selective reduction of nitrogen oxides by ethanol increases as the Al2O3 content increases, and is determined by the optimal silver content for which Ag + cations and Ag n nanoclusters form on the Al2O3 surface. The role of silver in…

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…

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…

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…

Active Site Design in a Core-Shell Nanostructured Catalyst for a One-Pot Oxidation Reaction

Shusuke Okada, Kohsuke Mori, Takashi Kamegawa, Michel Che, Hiromi Yamashita

Designing an active site: A new type of core-shell structured catalyst was prepared, with a uniform SiO2 core supporting Pd nanoparticles (NPs) covered with a Ti-containing mesoporous silica shell. Generated H2O2 on the inner Pd NP site could interact with the Ti oxide moieties within the mesopores…

Elaboration, characterization and properties of silica-based single-site heterogeneous photocatalysts

M. Che, K. Mori, H. Yamashita

This study concerns single-site heterogeneous photocatalysts, composed of isolated transition metals ions (single-sites) dispersed on silica-based supports, which can be used as photocatalysts. The first part gives the definition of single-site heterogeneous catalysts. The main difficulty to…

Enzymatic fuel cells solely supplied with unpurified cellobiose dehydrogenase and laccase in microorganism's culture supernatants

Sabine Sane, Corinna Heilemann, Pavel Salavei, Stefanie Rubenwolf, Claude Jolivalt, Catherine Madzak, Roland Zengerle, Peter J. Nielsen, Sven Kerzenmacher

Enzymatic electrodes have great potential for catalysing the direct conversion of chemical compounds into electricity with the use of redox enzymes. However, expensive and time-consuming enzyme purification and the frequent need to add mediators are considered as drawbacks of enzymatic electrodes.…

Understanding the pH effect on the magnesium corrosion by means of electrochemical impedance spectroscopy

Abdelmoheiman Zakaria Benbouzid, Oumaïma Gharbi, Mai T.T. Tran, Mireille Turmine, Vincent Vivier

The corrosion mechanism of magnesium has been the subject of several papers, aiming to explain all the reported phenomena occurring at the Mg/electrolyte interface in general, and the negative difference effect (NDE) particularly [1]. In fact, this phenomenon consists on an increase of the hydrogen…
