Influence of the pretreatment conditions on the performances of CeO2-supported gold catalysts in the Catalytic Wet Air Oxidation of carboxylic acids

Ngoc D. Tran, Michèle Besson, Claude Descorme, Katia Fajerwerg, Catherine Louis

Two series of ceria-supported gold catalysts (1 and 4 wt.% Au) were prepared by deposition-precipitation with urea. Depending on the gold loading, the pretreatment of the Au/CeO2 catalysts (calcination in air vs. reduction in hydrogen) had a great influence on the oxidation state of gold, and in…

Dispersion and hydrogenation activity of surfactant-stabilized Rh(0) nanoparticles prepared on different mesoporous supports

Maya Boutros, Guillaume Shirley, Thomas Onfroy, Franck Launay

Supported Rh(0) colloidal particles were prepared by the reduction of Rh(III) ions by sodium borohydride in the presence of N-N-dimethyl-N-cetyl-N-(2-hydroxyethyl) ammonium chloride (HEA16Cl), usually used as a stabilizing agent in solution. Tested supports were Na-Al-SBA-15, SBA-15 and CMK-3. In…

Kinetic effects in dehydration, rehydration, and isotopic exchange of bacterial photosynthetic reaction centers

Marco Malferrari, Francesco Francia, Alberto Mezzetti, Giovanni Venturoli, Klaus Gerwert

BACKGROUND:In IR difference spectroscopy of proteins and biological systems, as in many other biophysical techniques, experiments at different hydration levels, and after H/D or H216O/H218O exchange are particularly important, for band assignment and for mechanistic studies. OBJECTIVE:Evaluate the…

Incorporation of Nb(V) into BEA zeolite investigated by XRD, NMR, IR, DR UV-vis, and XPS

Stanislaw Dzwigaj, Yannick Millot, Christophe Methivier, Michel Che

Nb(x)SiBEA (x = 1.0, 1.5 Nb wt%) zeolites are prepared by a two-step postsynthesis method involving first the creation of vacant T-atom sites associated with silanol groups by dealumination of BEA zeolite by nitric acid solution and then by impregnation of the resulting SiBEA zeolite with the…

Comment on “Direct Decomposition of NO x over TiO 2 Supported Transition Metal Oxides at Low Temperatures”

Josefine Schnee, Laurent Delannoy, Guylène Costentin, Frédéric Meunier, Cyril Thomas

In a recent paper entitled "Direct decomposition of NO x over TiO 2 supported transition metal oxides at low temperatures", 1 Damma et al. report highly promising results on the catalytic direct decomposition of NO to N 2 and O 2 at temperatures as low as 100 °C, with excellent tolerance…

A combined experimental and theoretical study of the simultaneous occupation of SIa and SI0 sites in fully dehydrated K-LSX

Hazar Guesmi, Pascale Massiani, Habiba Nouali, Jean-Louis Paillaud

In the case of fully potassium exchanged X and LSX faujasites, it was reported from a single crystal X-ray study on zeolite X and preliminary powder X-ray diffraction (PXRD) study on zeolite LSX that K+ ions can be found concomitantly in both sites I and I' with partial or full occupancy of…

Simple and Specific Grafting of Antibacterial Peptides on Silicone Catheters

Coline Pinese, Said Jebors, Cécile Echalier, Patricia Licznar-Fajardo, Xavier Garric, Vincent Humblot, Christophe Calers, Jean Martinez, Ahmad Mehdi, Gilles Subra

To fight against nosocomial infection initiated by colonization of medical devices, a strategy enabling the direct and fast functionalization of silicone surfaces is proposed. This strategy proceeds in a site-specific way using original hybrid silylated antibacterial peptides. This safe and up-…

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…
