Characterization of Phosphate Species on Hydrated Anatase TiO2 Surfaces

Frederik Tielens, Christel Gervais, Géraldine Deroy, Maguy Jaber, Lorenzo Stievano, Cristina Coelho Diogo, Jean-Francois Lambert

The adsorption/interaction of KH2PO4 with solvated (100) and (101) TiO2 anatase surfaces is investigated using periodic DFT calculations in combination with GIPAW NMR calculations and experimental IR and solid state 17O, and 31P NMR spectroscopies. A complete and realistic model has been used to…

Efficiency of Polyoxometalate-Based Mesoporous Hybrids as Covalently Anchored Catalysts

Faiza Bentaleb, Ourania Makrygenni, Dalil Brouri, Cristina Coelho Diogo, Ahmad Mehdi, Anna Proust, Franck Launay, Richard Villanneau

Polyoxometalate (POM) hybrids have been covalently immobilized through the formation of amide bonds on several types of mesoporous silica. This work allows the comparison of three POM-based mesoporous systems, obtained with three different silica supports in which either the organic functions of…

Total oxidation of propene over Au/xCeO(2)-Al2O3 catalysts: Influence of the CeO2 loading and the activation treatment

Pandian Lakshmanan, Laurent Delannoy, Vincent Richard, Christophe Methivier, Claude Potvin, Catherine Louis

This study explores the reaction of oxidation of propene (1200 ppm) under excess oxygen (9%) over Au/xCeO(2)/Al2O3 catalysts (x = 1.5, 3, 5, and 10 wt% CeO2) to mimic the conditions of VOC decomposition. The present study reveals the influence of several factors that affect the oxidative…

Influence of the state of iron on CO oxidation on FeSiBEA zeolite catalysts

Izabela Hnat, Ireneusz Kocemba, Jacek Rynkowski, Thomas Onfroy, Stanislaw Dzwigaj

The influence of the state of iron on the catalytic properties of FexSiBEA zeolite in the oxidation of CO was investigated. Various FexSiBEA zeolites (x = 0.6, 1.0, 4.0 and 10 wt%) were prepared by a two-step post synthesis method. The presence of Fe(III) in tetrahedral coordination for low Fe…

Optimized immobilization of gold nanoparticles on planar surfaces through alkyldithiols and their use to build 3D biosensors

Anne-Laure Morel, Rose-Marie Volmant, Christophe Methivier, Jean-Marc Krafft, Souhir Boujday, Claire-Marie Pradier

This paper describes a controlled way to immobilize gold nanoparticles on planar gold surfaces and the use of the resulting 3D platform to build up a 3D biosensor. The surface was first functionalized by grafting hexanedithiol, this molecule has 2 thiol end groups, which enables its chemical…

Elaboration of a reusable immunosensor for the detection of staphylococcal enterotoxin A (SEA) in milk with a quartz crystal microbalance

Michèle Salmain, Mahsa Ghasemi, Souhir Boujday, Claire-Marie Pradier

An immunosensor with quartz crystal microbalance (QCM) detection operating in flow-through mode was set up for assaying staphylococcal enterotoxin A (SEA) in model buffer medium and in milk. This biosensor is label-free and operates in the direct format. Each step of construction of the sensing…

kinetics of the plasmon optical response of Au nanoparticles/TiO2 catalyst under O2 and H2 followed by differential diffuse reflectance spectroscopy

Yves Borensztein, Laurent Delannoy, Ruben G. Barrera, Catherine Louis

The changes in the optical properties of Au/TiO2 powder catalyst, prepared by the deposition-precipitation method, are measured in the visible range by use of a home-made diffuse differential reflectance spectrometer, when the ambient atmosphere is switched between H2 and O2. Two main features are…
