Metal–Support Interactions in Pt-WO 3 Heterostructures: Role of WO 3 Polymorphism

Isabel Gómez-Recio, Cyril Thomas, Christophe Méthivier, María Luisa Ruiz-González, José González-Calbet, David Portehault

Ionic exchange under soft conditions yields nanoplatelets of tungsten bronzes with an original crystal structure doped with cobalt, copper, platinum, and cesium cations (h′-MxWO3). The optimal orientation of the tunnel-based crystal structure, perpendicular to the basal plane of the nanoplatelets,…

Evidence of Pd segregation and stabilization at edges of AuPd nano-clusters in the presence of CO: A combined DFT and DRIFTS study

Beien Zhu, Gode Thrimurthulu, Laurent Delannoy, Catherine Louis, Christine Mottet, Jerome Creuze, Bernard Legrand, Hazar Guesmi

Combined Density Functional Theory (DFT) calculations and Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) were performed to study the distribution of Pd atoms in bimetallic AuPd nanoparticles in the presence of adsorbed CO. Compared to vacuum condition, the results showed…

Selective Catalytic Reduction of NO x over Au/Al2O3: Influence of the Gold Loading on the Promoting Effect of H2 in H2-Assisted C3H6-SCR of NO x

Tesnim Chaieb, Cyril Thomas, Sandra Casale, Catherine Louis, Laurent Delannoy

This article reports on the promotional effect of adding H2 to the reaction feed for the selective catalytic reduction of NO x with propene (H2–C3H6-SCR) over Au/Al2O3 catalysts. For this purpose, the influence of the Au loading in H2–C3H6-SCR was investigated. The H2 promoting effect in C3H6-SCR,…

Polarizable QM/Classical Approaches for the Modeling of Solvation Effects on UV–Vis and Fluorescence Spectra: An Integrated Strategy

Daniele Loco, Natalia Gelfand, Sandro Jurinovich, Stefano Protti, Alberto Mezzetti, Benedetta Mennucci

Hybrid methods combining quantum chemistry and classical models are largely used to describe solvent effects in absorption and emission processes of solvated chromophores. Here we compare three different formulations of these hybrid approaches, using a continuum, an atomistic, or a mixed…

EIS investigation of zinc dissolution in aerated sulphate medium. Part II: zinc coatings

Chantal Cachet, F. Ganne, Suzanne Joiret, Georges Maurin, J. Petitjean, Vincent Vivier, Robert Wiart

The kinetics of anodic dissolution and corrosion of zinc coatings deposited onto steel sheet either by electrodeposition or by hot dipping are investigated by electrochemical impedance spectroscopy in aerated sulfate medium. The results are compared with those obtained previously on pure bulk zinc…

Ionic liquid redox flow membraneless battery in microfluidic system

Nesrine Chaabene, Kieu Ngo, Mireille Turmine, Vincent Vivier

Redox flow batteries (RFBs) often require the presence of a physical membrane to separate the two compartments of the battery. The objective of this work is to develop a membraneless microfluidic redox flow battery (RFB) by using 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide…

Unusual behaviour of Au/ZnO catalysts in selective hydrogenation of butadiene due to the formation of a AuZn nanoalloy

Salim Derrouiche, Camille La Fontaine, Gode Thrimurtulu, Sandra Casale, Laurent Delannoy, Hélène Lauron-Pernot, Catherine Louis

The reaction of selective hydrogenation of butadiene performed in an excess of propene, which has been extensively studied over gold supported on different oxides and exhibited high selectivity to butenes, has been applied to the case of gold (1 wt%) supported on zinc oxide (8 m2 g−1), a strongly…

Characterization of zeolitic intraframework molybdenum sites

Gabriella Skara, Rafal Baran, Thomas Onfroy, Frank de Proft, Stanislaw Dzwigaj, Frederik Tielens

An integrated experimental and computational study was carried out on molybdenum loaded BEA zeolite in order to scrutinize the most stable state of the molybdenum site at various oxidation and hydration states. After a two-step post-synthetic process, the incorporation of Mo ions into the vacant T…

Elaboration de catalyseurs hétérogènes en milieu liquide ionique : nanoparticules métalliques (Au et Au-Pd) supportées sur dioxyde de titane, Heterogeneous catalysts preparation in ionic liquid media : titania-supported metallic nanoparticles (Au and Au-Pd)

Camella Oumahi

Ces travaux portent sur l'élaboration de catalyseurs hétérogènes en milieu liquide ionique (LI).
