Bimetallic Au-Pd catalysts for selective hydrogenation of butadiene: Influence of the preparation method on catalytic properties

N. El Kolli, L. Delannoy, C. Louis

Supported Au catalysts modified by the addition of small amount of Pd (Au/Pd atomic ratio (10) were prepared according to three different methods, co-deposition-precipitation with urea (DPU), deposition of colloids stabilised either by polyvinyl alcohol (PVA) or by tetrakis (hydroxypropyl)…

Density Functional Theory Modeling and Calculation of NMR Parameters: An ab Initio Study of the Polymorphs of Bulk Glycine

Lorenzo Stievano, Frederik Tielens, Irene Lopes, Nicolas Folliet, Christel Gervais, Dominique Costa, Jean-Francois Lambert

The three forms of glycine in the solid state, α, β, and γ are described and modeled by means of generalized-gradient approxn. (GGA) ab initio calcns. In particular, the location of the protons in each structure is studied. The vibrational frequencies and the NMR chem. shifts of 1H, 13C, and 15N in…

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…

Fe-clay-plate as a heterogeneous catalyst in photo-Fenton oxidation of phenol as probe molecule for water treatment

Haithem Bel Hadjltaief, Patrick da Costa, Patricia Beaunier, María Elena Gálvez, Mourad Ben Zina

A novel heterogeneous photo-Fenton plate catalyst was prepared by immobilizing iron species on the surface of natural Tunisian clay. The activity of this structured catalyst was assayed in the degradation of phenol under UV irradiation at two different wavelengths (245 nm, UVC, and 365 nm, UVA,…

Amplified plasmonic detection of DNA hybridization using doxorubicin-capped gold particles

Jolanda Spadavecchia, Ramesh Perumal, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

We show in this article that doxorubicin-modified gold nanoparticles (Au NP-DOX) can be used for the post-amplification of the wavelength shift of localized surface plasmon resonance (LSPR) signals after DNA hybridization events. We take advantage of the intercalation properties of DOX with guanine…

Electrodeposition of Co, Ni-based Alloys in Ionic Solutions and their Electrocatalytic Propert, Électrodéposition de alliages à base de Co, Ni en solutions ioniques et leurs propriétés électrocatalytiques

Yuelin Xie

The use of fossil energy, one of the main contributors to carbon emissions and a major source of pollution, has become a hot topic of discussion in recent years. Predicted energy shortages and the resulting environmental challenges are forcing mankind to look for alternatives to fossil fuels.…, Le développement de diverses applications utilisant l’hydrogène en tant que vecteur énergétique ouvre des voies prometteuses pour l'avenir. L’hydrogène peut être produit de différentes manières, l’une d’entre elles est l’électrolyse de l’eau et plus particulièrement sa réduction qui conduit à…

Low Temperature NOx Adsorption Study on Pd-Promoted Zeolites

Alessandro Porta, Tommaso Pellegrinelli, Lidia Castoldi, Roberto Matarrese, Sara Morandi, Stanislaw Dzwigaj, Luca Lietti

In this study Pd-promoted zeolites (BEA, FER, MFI and MOR) are synthesized and investigated for potential use in the low-temperature NOx adsorption. The catalysts are characterized by BET, XRD, UV–Vis and XRF, while the adsorption/desorption characteristics of the samples are investigated by NOx…

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-…

Gold nanoparticle-based localized surface plasmon immunosensor for staphylococcal enterotoxin A (SEA) detection

Maroua Ben Haddada, David Hu, Michèle Salmain, Lu Zhang, Chen Peng, Yi Wang, Bo Liedberg, Souhir Boujday

We describe the engineering of stable gold nanoparticle (AuNP) bioconjugates for the detection of staphylococcal enterotoxin A (SEA) using localized surface plasmon resonance (LSPR). Two types of AuNP bioconjugates were prepared by covalently attaching anti-SEA antibody (Ab) or SEA to AuNPs. This…

Influence of the nature and environment of manganese in Mn-BEA zeolites on NO conversion in selective catalytic reduction with ammonia

Rafal Baran, L. Valentin, J.-M. Krafft, T. Grzybek, P. Glatzel, Stanislaw Dzwigaj

Manganese-containing BEA zeolites, MnxSiBEA (x = 1–4 wt %) and Mn(I.E.)AlBEA, were prepared by a two-step postsynthesis method and a conventional wet ion-exchange, respectively, and applied as catalysts in the selective catalytic reduction of NO with ammonia (NH3-SCR). The physicochemical analysis…
