The controlled synthesis of metal-acid bifunctional catalysts: Selective Pt deposition and nanoparticle synthesis on amorphous aluminosilicates

Jadid E. Samad, Juliette Blanchard, Celine Sayag, Catherine Louis, John R. Regalbuto

The rational synthesis of metal-acid bifunctional catalysts based on aluminosilicates will involve control over which domain – alumina or silica – the metal can be deposited on, as well as the control of particle size. These factors determine the ratio and proximity of the metal and acid sites. The…

Ultrafast time-resolved quantum cascade laser diagnostic for enlightening the role of surface formate species in the photocatalytic oxidation of methanol

Josefine Schnee, Marco Daturi, Mohamad El-Roz

In the present work, a new quantum cascade laser (QCL)-assisted operando FT-IR setup was used to get direct insight into the relationship between the overall catalytic performance of TiO2 photocatalysts in the gas phase photooxidation of methanol at 25 °C, and the kinetics of intermediate surface…

Comprehension of cellulose depolymerisation mechanisms induced by iron ions, Compréhension des mécanismes de dépolymérisation de la cellulose induits par les ions fer

Degradation of paper by iron gall inks (IGI) is a challenging issue for written heritage conservation. These inks consist of a mixture of iron(II) sulphate, tannins and gum Arabic, and are therefore acidic and iron-rich. Hence, paper degradation by IGI is often attributed to a combination of acid…, La dégradation du papier par les encres ferrogalliques (EFG) est un défi pour la conservation du patrimoine écrit. Ces encres, composées d'un mélange de sulfate de fer (II), de tannins et de gomme Arabique, sont acides et riches en fer. Par conséquent, les mécanismes de dégradation des…

This work addresses the issue of soil and water decontamination by exploring environmentally friendly decontamination strategies that involve the degradation of organic contaminants, particularly antibiotics. Building on the work of Ardo et al. (2015), this study examines the degradation of…, Ce travail aborde la problématique de la dépollution des sols et des eaux en explorant des stratégies de dépollution respectueuses de l'environnement mettant en jeu la dégradation de contaminants organiques, notamment les antibiotiques.

Identification and Location of Iron Species in Fe/SBA-15 Catalysts: Interest for Catalytic Fenton Reactions

Cécile Cornu, Jean-Luc Bonardet, Sandra Casale, Anne Davidson, Sebastien Abramson, Gilles André, Florence Porchet, Ivana Grcic, Vesna Tomasic, Dinko Vujevic

We have used a single SBA-15 silica batch (mesopore diameter of 7.1 nm) and the two-solvent impregnation technique with either pentane or cyclohexane to prepare model samples in which an initial aqueous solution of salt precursor (iron nitrate or iron chloride) is deposited mainly inside silica…

Influence of Large Magnetic Field Gradients at the Electrochemical Interface

Jinu Kurian, Peter Dunne, Vincent Vivier, Gwenael Atcheson, Ruslan Salikhov, Ciaran Fowley, Munuswamy Venkatesan, Olav Hellwig, Michael Coey, Bernard Doudin

We investigate how a model single-electron-exchange electrochemical reaction can be influenced by a magnetic field, B, which is a combination of an external applied field and the stray field generated by a Co/Pt multilayer thin film stack with preferred perpendicular magnetization. The Lorentz…
