Nature of the active sites in CO oxidation on FeSiBEA zeolites

Ireneusz Kocemba, Jacek Rynkowski, Jacek Gurgul, Robert P. Socha, Kazimierz Łątka, Jean-Marc Krafft, Stanislaw Dzwigaj

FeSiBEA zeolites containing 1 wt% of iron were prepared by a two-step postsynthesis method in acidic (pH = 2.6) (Fe1.0SiBEA(w)) and alkaline (pH = 10) (Fe1.0SiBEA(p)) conditions. The structure of the studied materials, their acidity as well as the nature and environment of iron present in the…

Chimie : un vecteur vert

Jacques Maddaluno, Claire-Marie Pradier, Anne Imberty, Dominique Massiot

Les faits, longtemps sujets à discussion, sont désormais là. Le cinquième rapport du GIEC (2013) qualifie d'« extrêmement probable » un lien entre les dérèglements climatiques observés depuis 1950 et les variations de la composition de l'atmosphère terrestre provoqués par l'…

On the influence of water traces on the acidity measurement of amorphous aluminosilicates

Juliette Blanchard, Jean-Marc Krafft, Colin Dupont, Céline Sayag, Toshikazu Takahashi, Hiroyuki Yasuda

For the measurement of their acidity, amorphous aluminosilicates are beforehand treated at temperature of 450 • C or higher in order to remove water adsorbed on their surface. We will show in this study that, during the standard course of an acidity measurement by low temperature CO adsorption,…

Characterizing a supported catalyst : a methodological approach

Eric Marceau

The characterization of supported catalysts requires the combination of several physicochemical and spectroscopic techniques in order to investigate the support and active phase composition, morphology and reactivity. The most common techniques used at the laboratory are detailed in this chapter…

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…

Identification of Surface Basic Sites and Acid–Base Pairs of Hydroxyapatite

Sarah Diallo-Garcia, Manel Ben Osman, Jean-Marc Krafft, Sandra Casale, Cyril Thomas, Jun Kubo, Guylène Costentin

The Lewis and Brønsted basic properties of a stoichiometric hydroxyapatite (HAp) were investigated by infrared spectroscopy following the adsorption and desorption processes of a Lewis acidic molecule, CO2, and a Brønsted acidic molecule, C2H2. CO2 interacts with basic OH– and O2– of PO43– groups…

Lewis acido-basic interactions between CO2 and MgO surface: DFT and DRIFT approaches

Damien Cornu, Hazar Guesmi, Jean-Marc Krafft, Hélène Lauron-Pernot

Combined experimental infrared (IR) and theoretical approaches have been carried out in an attempt to specify the actual structure of the CO2 species adsorbed on the magnesium oxide surface. The interaction of CO2 with regular sites of the MgO(100), (111) and (110) surfaces as well as MgO(100)…

Sensing the Charge State of Single Gold Nanoparticles via Work Function Measurements

Yingjie Zhang, Olivier Pluchery, Louis Caillard, Anne-Félicie Lamic-Humblot, Sandra Casale, Yves J. Chabal, Miquel Salmeron

Electrostatic interactions at the nanoscale can lead to novel properties and functionalities that bulk materials and devices do not have. Here we used Kelvin probe force microscopy (KPFM) to study the work function (WF) of gold nanoparticles (NPs) deposited on a Si wafer covered by a monolayer of…

Polyethylene glycol Gold-Nanoparticles: Facile Nanostructuration of Doxorubicin and its complex with DNA molecules for SERS detection

Jolanda Spadavecchia, Ramesh Perumal, Sandra Casale, Jean-Marc Krafft, Christophe Methivier, Claire-Marie Pradier

We report the synthesis of dicarboxylic acid-terminated polyethylene-glycol (PEG)-gold nanoparticles by a simple one-step method, and their further use to form nanostructured surfaces for biomolecule immobilization. The synthesized nano-scale particles were conjugated with probe/target…
