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…

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…

Enhanced Vibrational Spectroscopies as Tools for Small Molecule Biosensing

Souhir Boujday, Marc Lamy de La Chapelle, Johannes Srajer, Wolfgang Knoll

In this short summary we summarize some of the latest developments in vibrational spectroscopic tools applied for the sensing of (small) molecules and biomolecules in a label-free mode of operation. We first introduce various concepts for the enhancement of InfraRed spectroscopic techniques,…

Orientation of a Trametes versicolor laccase on amorphous carbon nitride coated graphite electrodes for improved electroreduction of dioxygen to water

Achraf Blout, Florence Billon, Christophe Calers, Christophe Méthivier, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Amorphous carbon nitride (a-CNx) thin films were used for the first time as electrode materials in the elaboration of biofuel cell cathodes as a consequence of i) the natural presence of amine type functional groups and ii) the ease to generate carboxylic acid groups on their surface with the help…

Spectroscopic and Electrochemical Study of the Adsorption of [Co(en) 2 Cl 2 ]Cl on γ-Alumina: Influence of the Alumina Ligand on Co (III)/(II) Redox Potential

Vincent Vivier, François Aguey, Jeanine Fournier, Jean-François Lambert, Fethi Bedioui, Michel Che

UV−visible and Raman spectroscopies as well as electrochemical techniques have been used to characterize cis- and trans-[Co(III)(en)2Cl2]Cl (en = ethylenediamine) complexes and the γ-alumina-supported cis-Co(III) complex. It is shown that the electrochemical reduction of these complexes occurs…
