Heterogeneous catalyst preparation in ionic liquids: Titania supported gold nanoparticles

Camella Oumahi, Jean Lombard, Sandra Casale, Christophe Calers, Laurent Delannoy, Catherine Louis, Xavier Carrier

This work reports the use of ionic liquids (ILs) as solvent for the synthesis of Au/TiO2 heterogeneous catalysts. It is shown that the versatility of the physico-chemical properties of ILs makes them interesting solvents for a broad control of supported metal nanoparticles (NPs) size and for a fine…

Photoelectrochemical properties of nanocrystalline ZnS discrete versus continuous coating of ZnO nanorods prepared by electrodeposition

A. Brayek, S. Chaguetmi, M. Ghoul, I. Ben Assaker, A. Souissi, L. Mouton, P. Beaunier, S. Nowak, F. Mammeri, R. Chtourou, S. Ammar

We developed nanostructured photoanodes for photoelectrochemical (PEC) water splitting and hydrogen generation. They are based on ZnO nanorods electrodeposited on conductive ITO glass on which ZnO@ZnS heterojunctions were formed using two different approaches. In the first case, the ZnO nanorods…

Hydroxyapatite: A Matrix for Metal Exsolution Leading to Highly Dispersed Catalytically Active Species

Josefine Schnee, Ferdaous Ben Romdhane, François Devred, Antoine Miche, Alixandre Magerat, Diane Reja, Eric Gaigneaux, Marco Daturi, Cyril Thomas, Guylène Costentin

Hydroxyapatite (Ca10(PO4)6(OH)2, or HAp) -the main mineral component of bones and teeth -is a material of great interest not only in biomedical applications but also in heterogeneous catalysis. Its framework Ca 2+ cations can be substituted by a wide variety of catalytically active metals (Cu 2+ ,…

Poly(methyl methacrylate) Nanoparticles Grafted with Gold‐L‐Cysteine as a Water Cleaning Material for the Photocatalytic Degradation of Paracetamol

Karima Agoudjil, Nabila Haddadine, Anne Davidson, Siham Barama, Khaled Abouzeid, Akila Barama, Mohamed Selmane, Naima Bouslah, Ahmed Benaboura, Régis Barillé, M. Samy El-Shall

Here, we report the photocatalytic degradation of aqueous paracetamol (Acetaminophen or N-acetyl-p-aminophenol, APAP) as a drug model under visible light in presence of opal and inverse opal photonic crystals (PC) derived from gold-L-cysteine and grafted on poly(methyl methacrylate) (PMMA)…

Metallomics in deep time and the influence of ocean chemistry on the metabolic landscapes of Earth's earliest ecosystems

Keyron Hickman-Lewis, Barbara Cavalazzi, Stéphanie Sorieul, Pascale Gautret, Frédéric Foucher, Martin Whitehouse, Heejin Jeon, Thomas Georgelin, Charles Cockell, Frances Westall

Modern biological dependency on trace elements is proposed to be a consequence of their enrichment in the habitats of early life together with Earth's evolving physicochemical conditions; the resulting metallic biological complement is termed the metallome. Herein, we detail a protocol for…

Catalytic behaviour of hybrid LNT/SCR systems: Reactivity and in situ FTIR study

L. Castoldi, R. Bonzi, L. Lietti, P. Forzatti, S. Morandi, G. Ghiotti, S. Dzwigaj

The NOx storage-reduction over the single Pt-Ba/Al2O3 and Fe-ZSM-5 systems and over the hybrid Pt-Ba/Al2O3 + Fe-ZSM-5 systems, both physically mixed and in dual bed configuration with the SCR catalyst placed downstream of the LNT catalyst, is systematically investigated by Isothermal Step…

L’Unité Mixte de Recherche est la brique élémentaire, souple et pérenne d’un paysage de la recherche en évolution rapide. De nombreux dispositifs viennent structurer l’activité de ces équipes pour faire émerger des pôles de recherche, consolider le maillage des réseaux nationaux, identifier les…, Mixed research units are building blocks, flexible but permanent, in rapidly evolving fields of research. Several measures shape the activities of research teams and thus give rise to “poles of research”. They also help consolidate national networks, identify strong points, boost the sharing of top…

In situ XAFS study of the thioresistance of metallic Ru supported on HYd zeolite

Juliette Blanchard, K. Kyoko Bando, Christophe Geantet, Takashi Matsui, Michèle Breysse, Yuji Yoshimura

In situ XAFS at the Ru K edge was used to investigate the reduction of Ru(NH3)63+ supported on HYd zeolite, and the evolution of the reduced sample in the presence of sulfur (350 ppm and 2%H2S/H2) at 523K. After reduction at 673K very small Ru° nanoparticules are formed which interact strongly with…

Preparation of two series of VxSiBeta zeolite catalysts with V centres in framework and extra-framework positions and their application in selective oxidation of methanol

Maciej Trejda, Yannick Millot, Karolina Chalupka, Stanislaw Dzwigaj

Two series of V-containing Beta zeolites have been prepared by contacting of the aqueous NH 4 VO 3 solution with two SiBeta zeolites at pH = 2.5 and 6, respectively. Because of the presence in NH 4 VO 3 solution at pH = 2.5 mainly monomeric VO 2 + ions, vanadium have been easily incorporated into…
