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…

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…

Mn-analcime: Synthesis, characterization and application to cyclohexene oxidation

Amal Bejar, Semy Ben Chaabene, Maguy Jaber, Jean-François Lambert, Latifa Bergaoui

The hydrothermal synthesis of Mn-analcime was performed by mixing manganese(II) carbonate, silicic acid and aluminum nitrate in a basic medium in the 120–175 °C temperature range for 6–72 h. Different Mn/Al ratios were used. The obtained samples were characterized by powder XRD, N2 physical…

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…

Molybdenum oxide model catalysts and vanadium phosphates as actual catalysts for understanding heterogeneous catalytic partial oxidation reactions: A contribution by Jean-Claude Volta

Jacques C. Védrine, Graham J. Hutchings, Christopher J. Kiely

This review summarises and expands part of the work that Jean Claude Volta carried out during his scientific career at the Institut de Recherches sur la Catalyse (IRC), CNRS, University of Lyon in France. The first part deals with the structure sensitivity of molybdenum oxide (MoO3) for oxidation…

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…

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…
