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…

Ordered mesoporous “one-pot” synthesized Ni-Mg(Ca)-Al2O3 as effective and remarkably stable catalysts for combined steam and dry reforming of methane (CSDRM)

Karam Jabbour, Pascale Massiani, Anne Davidson, Sandra Casale, Nissrine El Hassan

Two series of Nix% (x: 5–10 wt%) and Ni5%M5% (M: Ca or Mg) containing mesoporous Al2O3 catalysts were prepared by “one-pot” synthesis following an evaporation-induced self-assembly (EISA) method. After reduction, the catalysts showed very high Ni dispersion within the structured oxide matrix giving…

Electronic structure investigation of biphenylene films

R. Totani, C. Grazioli, Tiantian Zhang, I. Bidermane, J. Lüder, M. de Simone, M. Coreno, B. Brena, L. Lozzi, C. Puglia

Photoelectron Spectroscopy (PS) and Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy have been used to investigate the occupied and empty density of states of biphenylene films of different thicknesses, deposited onto a Cu(111) crystal. The obtained results have been compared to…

Speciation of Ruthenium as a Reduction Promoter of Silica-Supported Co Catalysts: A Time-Resolved in Situ XAS Investigation

Jingping Hong, Eric Marceau, Andrei Y. Khodakov, Lucia Gaberová, Anne Griboval-Constant, Jean-Sébastien Girardon, Camille La Fontaine, Valérie Briois

Complete reduction of the metal phase in cobalt-containing catalysts is often difficult to reach and can be promoted by a small amount of noble metals. Because these costly promoters are introduced in a very low quantity, their speciation and their chemical interaction with cobalt have seldom been…

Nouvelles biocathodes graphite/nitrure de carbone amorphe/laccase pour la réduction de l'oxygène par transfert électronique direct

Achraft Blout, Alain Pailleret, Hubert Perrot, Claude Jolivalt

Les enzymes constituent une alternative intéressante aux catalyseurs métalliques car elles possèdent une meilleure sélectivité et des performances catalytiques souvent plus élevées. Elles peuvent être utilisées dans différents types de dispositifs électrochimiques comme les piles à combustible1.…

Influence of Metal Salts Addition on Physical and Electrochemical Properties of Ethyl and Propylammonium Nitrate

David Ausín, José Trenzado, Mireille Turmine, Luis Varela, Oscar Cabeza, Elisa González Romero, Luisa Segade

In this work, we deepen in the characterization of two protic ionic liquids (PILs), ethylammonium nitrate (EAN) and propylammonium nitrate (PAN). With this aim, we determined the influence of inorganic nitrate salts addition on their physical properties and their electrochemical potential window (…

Gold Nanoparticles on Oxide-Free Silicon-Molecule Interface for Single Electron Transport

Louis Caillard, Oliver Seitz, Philip M. Campbell, Rachel P. Doherty, Anne-Félicie Lamic-Humblot, Emmanuelle Lacaze, Yves J. Chabal, Olivier Pluchery

Two different organic monolayers were prepared on silicon Si(111) and modified for attaching gold nanoparticles. The molecules are covalently bound to silicon and form very ordered monolayers sometimes improperly called self-assembled monolayers (SAM). They are designed to be electrically…

Lead halide perovskite nanocrystals have attracted attention in the field of nanocrystal-based light-emitting diode and solar cells, because their devices showed high performances in only a few years. Among them, CsPbI3 is a promising candidate for solar cell design in spite of a too wide band gap…
