Proving ligand structure-reactivity correlation on multinuclear copper electrocatalysts supported on carbon black for the oxygen reduction reaction

Ricardo Venegas, Karina Muñoz-Becerra, Sophie Juillard, Lin Zhang, Rubén Oñate, Ingrid Ponce, Vincent Vivier, Francisco J Recio, Carlos M Sánchez-Sánchez

Bioinspired transition-metal catalysts seek to mimic the specific active site of metalloenzymes, as the multicopper oxidase, that can efficiently reduce dioxygen to water via a complete 4-electrons mechanism at low overpotential. However, the multicopper oxidase enzymes lack stability under…

Characterization of omega-functionalized undecanethiol mixed self-assembled monolayers on Au(111): A combined polarization modulation infrared reflection-absorption spectroscopy/X-ray photoelectron spectroscopy/periodic density functional theory study

Frederik Tielens, Dominique Costa, Vincent Humblot, Claire-Marie Pradier

The structure of undecanethiol self-assembled monolayers (SAMs) on Au(111) with -COOH and -OH tail groups has been characterized by combining experimental and theoretical techniques. The pure and mixed 1:1 SAMs were investigated. It was found using polarization modulation infrared reflection-…

Rational design of a CO2-resistant toluene hydrogenation catalyst based on FT-IR spectroscopy studies

Julien Scalbert, Cécile Daniel, Yves Schuurman, Cyril Thomas, Frédéric C. Meunier

Rhodium highly dispersed on alumina becomes partly poisoned by strongly bound CO when used for toluene hydrogenation at 348 K in the presence of CO2. Operando FT-IR analysis enabled to observed CO(ads) build up over the sample, while no CO(gas) could be measured in the reactor effluent. Analyses…

Introduction to Clay–Polymer Nanocomposites (CPN)

F Bergaya, Christian Detellier, Jean-François Lambert, G Lagaly

Clay mineral–polymer nanocomposites were described for the first time in 1993. Since that date, they were the subject of thousands of research papers. Clay mineral–polymer nanocomposites must be carefully distinguished from microcomposites and intercalated composites. The following chapters…

An UV-Visible study of the stability of the ruthenium hexaammine cation in BEA zeolites—comparison with NaY

Pascale Massiani, Perla Castillo-Villalon, Jorge Ramirez, Marie-Jeanne Peltre, Catherine Louis

A series of Ru/zeolites with Ru content in the range of 1–7 wt.% was prepared by cationic exchange in an aqueous Ru(NH3)6Cl3 solution, at room temperature, of two H–BEA (different particle sizes but same Si/Al ratio of 13), a Cs–BEA (Si/Al 1⁄4 13) and a NaY (Si/Al 1⁄4 2.4), zeolitic supports. The…

Stabilization of hexagonal close-packed metallic nickel for alumina-supported systems prepared from Ni(II) glycinate

Eric Marceau, Vicente Rodriguez-Gonzalez, Michel Che, Patricia Beaunier, Cyrille Train

The decomposition in flowing argon of the neutral complex [NiII(glycinate)2(H2O)2] leads to a mixture of face-centered cubic (fcc) and hexagonal close-packed (hcp) metallic nickel. The latter is the main phase when the Ni(II) complex is supported on alumina. Unlike most hexagonal Ni phases…

Conversion of syngas-derived C 2 + mixed oxygenates to C 3 –C 5 olefins over Zn x Zr y O z mixed oxide catalysts

Colin Smith, Vanessa Lebarbier Dagle, Matthew Flake, Karthikeyan K. Ramasamy, Libor Kovarik, Mark Bowden, Thomas Onfroy, Robert A. Dagle

In this study we report on a ZnxZryOz mixed oxide type catalyst capable of converting a syngas-derived C2+ mixed oxygenate feedstock to isobutene-rich olefins. Aqueous model feed comprising of ethanol, acetaldehyde, acetic acid, ethyl acetate, methanol, and propanol was used as representative…

Metallic nanoparticles (NPs) have many applications in catalysis. Some of them (gold, silver, copper) have a visible absorption resulting from the excitation of the surface plasmon by an external electromagnetic field. In this project, we propose to couple the catalytic properties of gold-based…, Les nanoparticules (NPs) métalliques ont de nombreuses applications en catalyse. Certaines d’entre elles (or, argent, cuivre) présentent une absorption dans le visible résultant de l’excitation du plasmon de surface par un champ électromagnétique extérieur.
