Incorporation of Mo into the Vacant T-Atom Sites of the Framework of BEA Zeolite as Mononuclear Mo Evidenced by XRD and FTIR, NMR, EPR, and DR UV-Vis Spectroscopies

Rafal Baran, Frédéric Averseng, Yannick Millot, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A MoSiBEA zeolite has been prepared by a two-step postsynthesis procedure that consists of first creating the vacant T-atom sites with associated silanol groups by treatment of TEABEA zeolite with nitric acid and then incorporating Mo ions into the vacant T-atom sites by solid-state ion exchange at…

Identification of cationic and oxidic caesium species in basic Cs-overloaded BEA zeolites

Pascale Massiani, C. Bisio, Katia Fajerwerg, L. Sordelli, L. Stievano, E.R. Silva, S. Coluccia, G. Martra

A parent acidic H-BEA with crystallites very small in size and high external surface area was used to prepare a series of materials loaded with increasing Cs+ contents by firstly ion-exchange and then impregnation with CsOH solutions. The monitoring of the ion- exchange process by chemical analysis…

Tuning Surface Chirality of Adsorbed Gly-Pro Dipeptide/Cu(110) by Changing its Chemical Form via Electrospray Deposition.

Christophe Méthivier, Hervé Cruguel, Dominique Costa, Claire-Marie Pradier, Vincent Humblot

By changing the Ultra High Vacuum (UHV) deposition method, classical sublimation versus electrospray ionization, one can tune the chemistry of a chiral dipeptide molecule (Gly-Pro, GP), when adsorbed on a Cu(110) surface, from anionic to zwitterionic, respectively. This chemical shift will…

Catalyseur hybride métal-zéolithe pour l'oxydation électrochimique de l'acide formique

Lu Zhang, J.V. Perales-Rondon, Angélica Thomère, Juliette Blanchard, Carlos M Sánchez-Sánchez, Vincent Vivier

La production d’énergie par voie électrochimique peut être envisagée comme un substitut à l’utilisation de combustibles fossiles ou nucléaires. Parmi les différents composants d’une pile à combustible, l’électrocatalyseur joue un rôle major. [1] Les zéolithes sont des aluminosilicates cristallins…

Combined ATR-FTIR and DFT Study of Cyclohexanone Adsorption on Hydrated TiO2 Anatase Surfaces

Ana Rita Almeida, Monica Calatayud, Frederik Tielens, Jacob A. Moulijn, Guido Mul

The adsorption of cyclohexanone on different planes ((100), (101), and (001)) of anatase TiO2, with variable level of hydration, was evaluated by density functional theory (DFT) calculations. Surface hydration was found to affect the cyclohexanone adsorption enthalpy and the calculated infrared…

Detection of hydrogen peroxide using dioxazaborocanes: elucidation of the sensing mechanism at the molecular level by NMR and XPS measurements

Thomas Caron, Pascal Palmas, Céline Frénois, Christophe Méthivier, Eric Pasquinet, Claire-Marie Pradier, Françoise Serein-Spirau, Lionel Hairault, Pierre Montméat

A fluorescent dioxazaborocane was synthesised and characterized, in order to study its turn-off sensing process for hydrogen peroxide detection. The exposure of the dioxazaborocane to diluted vapours of H2O2 led to a strong non reversible quenching of the fluorescence. Both NMR and XPS analyses…

Fluidized bed plasmas reactor for catalyst synthesis and pretreatment. Application for pollution abatement in stationary and mobile sources

Marjorie Foix, Cedric Guyon, Michael Tatoulian, Patrick da Costa

The prepn. of automotive catalysts and com. oxidn. catalysts in stationary sources use a large amt. of noble metal precursors. Moreover, during their prepn. high energy (gas and temp.) is necessary for treatment processes. In order to develop a higher sustainable process, the plasma-assisted…
