Mechanistic Study of Cast and 3D-Printed Stainless Steel Electropolishing in Acid Media and Deep Eutectic Solvents

Chloé Rotty, Marie-Laure Doche, Audrey Mandroyan, Vincent Vivier, Jean-Yves Hihn

The mechanistic analysis of the electropolishing procedure of stainless steel (SS) was revisited using electrochemical impedance spectroscopy. Firstly, the control of the dissolution reaction by diffusion was confirmed with the linear dependence of the limiting current density as a function of the…

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,…

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…

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-…

Selective Hydrogenation of Butadiene over Non-noble Bimetallic Catalysts, Catalyseurs bimétalliques à base de métaux non nobles pour l'hydrogénation sélective du Butadiène

Zhao Wang

This work investigates the preparation and characterization of titania-supported non-noble bimetallic Cu-Zn, Ni-Zn and Fe-Zn catalysts with various atomic ratios and their catalytic properties for the selective hydrogenation of polyunsaturated hydrocarbons. Co-deposition-precipitation with urea (…, Ce travail porte sur la préparation et la caractérisation de catalyseurs bimétalliques Cu-Zn, Ni-Zn et Fe-Zn supportés sur TiO2 avec des rapports atomiques variables et sur l'étude de leurs propriétés catalytiques pour l'hydrogénation sélective d'hydrocarbures polyinsaturés.

Chiral Ammonium-Capped Rhodium(0) Nanocatalysts: Synthesis, Characterization, and Advances in Asymmetric Hydrogenation in Neat Water

Elodie Guyonnet Bil É, Elodie Cortelazzo-Polisini, Audrey Denicourt-Nowicki, Rita Sassine, Franck Launay, Alain Roucoux

Optically active amphiphilic compounds derived from N-methylephedrine, N-methylprolinol, or cinchona derivatives possessing bromide or chiral lactate counterions were efficiently used as protective agents for rhodium(0) nanoparticles. The full characterization of these surfactants and the obtained…

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…
