Electrodeposition and soft oxidation of nickel‑iron hydroxides: An efficient two-step approach for the synthesis of highly active and stable iron-rich NiFe-LDHs with controlled Ni/Fe composition for oxygen evolution reaction

Yakoub Smati, Divino Salvador Ramírez-Rico, Antoine Miche, Jean-Marc Krafft, David Montero, Mireille Turmine, Vincent Vivier, Julien Reboul, Juliette Blanchard

Nickel‑iron layered double hydroxides (NiFe-LDHs) are promising low-cost and active electrocatalysts for the alkaline oxygen evolution reaction (OER), yet conventional synthesis methods face two key limitations: (i) poor control over the Ni/Fe atomic ratio and (ii) difficulty in producing active,…

Importance of the Nature of the Active Acid/Base Pairs of Hydroxyapatite Involved in the Catalytic Transformation of Ethanol to n ‐Butanol Revealed by Operando DRIFTS

Manel Ben Osman, Jean‐marc Krafft, Cyril Thomas, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Operando DRIFTS is used to identify the nature and the role of the surface sites of hydroxyapatites (HAps) involved in the catalytic transformation of ethanol to n‐butanol. The surface processes occurring upon a first reaction step followed by a step under He flow greatly influence the reactivity…

EIS investigations of the oxygen reduction reaction at the cathode of an enzymatic biofuel cell

Achraft Blout, Florence Billon, Hubert Perrot, Claude Jolivalt, Alain Pailleret

Enzymatic biofuel cells (EBCs) have been extensively studied over the last ten years in view of their application as implantable devices [1,2] as they have been shown indeed to reach the power required for small electronic devices. In EBCs, redox reactions occurring at the cathode and the anode are…

Porosity Design of Shaped Zeolites for Improved Catalyst Lifetime in the Methanol-to-Hydrocarbons Reaction

Rogéria Bingre, Renna Li, Qiang Wang, Patrick Nguyen, Thomas Onfroy, Benoit Louis

Additional porosity, such as meso-and macropores, was introduced in zeolite extrudates with the intention intuit of improving the effective diffusivity of the catalysts. The samples were characterized in depth by nitrogen adsorption-desorption, mercury intrusion porosimetry, ammonia temperature…

Hydrodeoxygenation of Furfural over Unsupported, SiO 2 ‐supported or Metal‐promoted Mo Carbides: Tunning the Selectivity between 2‐Methylfuran and C 10 Furoins Diesel Precursors

Letícia Sosa, Priscilla de Souza, Raphaela Rafael, Robert Wojcieszak, E. Marceau, Sébastien Paul, Valérie Briois, Fabio Noronha, Fabio Toniolo

Abstract The hydrodeoxygenation of furfural (FF) over Mo carbides in liquid phase at 200 °C, 30 bar of H 2 for 4 h in 2‐butanol was investigated. Unsupported and SiO 2 ‐supported Mo carbide with different crystallographic phases (β‐Mo 2 C/SiO 2 and α‐MoC/SiO 2 ), and in the presence of Cu and Ni as…

Electrical surface properties of nanoporous alumina membranes: influence of nanochannels’ curvature, roughness and composition studied via electrokinetic experiments

Ali Vakilinejad, Emmanuelle Dubois, Laurent Michot, Marie Jardat, Didier Lairez, Serge Durand-Vidal, Clément Guibert, Nicolas Jouault

Among classical nanoporous oxide membranes, anodic aluminum oxide (AAO) membranes, made of non-connected, parallel and ordered nanochannels, are very interesting nanoporous model systems widely used for multiple applications. Since most of these applications involve local phenomena at the…
