Supported Cu Nanoparticles as Selective and Stable Catalysts for the Gas Phase Hydrogenation of 1,3-Butadiene in Alkene-Rich Feeds

Giorgio Totarella, Rolf Beerthuis, Nazila Masoud, Catherine Louis, Laurent Delannoy, Petra de Jongh

Supported copper nanoparticles are a promising alternative to supported noble metal catalysts, in particular for the selective gas phase hydrogenation of polyunsaturated molecules. In this article, the catalytic performance of copper nanoparticles (3 and 7 nm) supported on either silica gel or…

On the use of a constant phase element (CPE) in electrochemistry

Samantha Michelle Gateman, Oumaïma Gharbi, Hercílio Gomes De Melo, Kieu Ngo, Mirelle Turmine, Vincent Vivier

Several techniques can be used to experimentally determine the interfacial capacitance of an electrode, which is a crucial parameter used for quantifying the efficiency of supercapacitors. However, the values obtained from cyclic voltammetry can be significantly different from those extracted from…

Beneficial effect of gelatin on iron gall ink corrosion

Alice Gimat, Anne Michelin, Pascale Massiani, Véronique Rouchon

Iron gall Inks corrosion causes paper degradation (browning, embrittlement) and treatments were developed to tackle this issue. They often include resizing with gelatin to reinforce the paper and its cellulosic fibers (of diameter approx. 10 µm). This work aimed at measuring the distribution of ink…

Covalent immobilization of glucose oxidase on mesocellular silica foams: Characterization and stability towards temperature and organic solvents

Noemie Balistreri, Dorian Gaboriau, Claude Jolivalt, Franck Launay

Glucose oxidase (GOx) immobilization onto mesoporous SBA-15 silica and two mesocellular foams (MCF) characterized by similar surface area and pore volumes but different pore/cell dimensions was examined. The covalent grafting of the enzyme through amide bonds was evidenced by controlling pH…

Identification of the silver state in the framework of Ag-containing zeolite by XRD, FTIR, photoluminescence, 109 Ag NMR, EPR, DR UV-vis, TEM and XPS investigations

Nataliia Popovych, Pavlo Kyriienko, Sergiy Soloviev, Rafal Baran, Yannick Millot, Stanislaw Dzwigaj

Silver has been identified in the framework of AgxSiBEA zeolites (where x = 3–6 Ag wt%) by the combined use of XRD, 109Ag MAS NMR, FTIR, diffuse reflectance UV-visible, EPR and XPS spectroscopy. The incorporation of Ag ions into the framework of SiBEA zeolite has been evidenced by XRD. The…

Improvements in photostability and sensing properties of EuVO₄ nanoparticles by microwave-assisted sol–gel route for detection of H₂ O₂ vapors

Chrystel Ambard, Natacha Duée, Franck Pereira, David Portehault, Christophe Méthivier, Claire-Marie Pradier, Clément Sanchez

The inorganic thin-film fluorescence probe, with the advantages of long life span and high sensitivity, has attracted much attention in explosive detection. The poor ultraviolet absorption and lack of an aromatic ring make peroxide-based explosives very hard to detect. As the signature compound of…

Converting silicon nanoparticles into nickel iron silicide nanocrystals within molten salts for water oxidation electrocatalysis

Yang Song, Sandra Casale, Antoine Miche, David Montero, Christel Laberty-Robert, David Portehault

We synthesize metal silicide electrocatalysts for water oxidation, by using the high reactivity of silicon nanoparticles and the unique stability and low vapor pressure of molten salt solvents. We can then perform liquid-phase synthesis under vacuum at 300-400 C. This strategy yields FeSi, Ni 2 Si…
