CO- and N2-FTIR Characterisation of Oxidised Rhodium Species Supported on Ce0.68Zr0.32O2

Céline Fontaine-Gautrelet, Jean-Marc Krafft, Olivier Gorce, Françoise Villain, Gérald Djéga-Mariadassou, Cyril Thomas

The identification of Rh oxidised species of a Rh(0.29)/Ce0.68Zr0.32O2 catalyst, exhibiting peculiar CO-O2 kinetics [Manuel et al., J. Catal. 2004, 224, 269], is addressed. For this purpose, various catalysts are studied by XANES, CO- and N2-FTIR, and benzene hydrogenation. The results obtained,…

Lipase-embedded Silica Nanoparticles with Oil-filled Core-Shell Structure: Stable and Recyclable Platforms for Biocatalysts

Yasutaka Kuwahara, Takato Yamanishi, Takashi Kamegawa, Kohsuke Mori, Michel Che, Hiromi Yamashita

Lipase enzyme was embedded within silica nanoparticles with oil-filled core-shell structure. The enzyme embedded within such architecture retained all of its activity and showed high catalytic performance both in water and in organic media with optimal stability and recyclability.

Coordination chemistry approach for the end-to-end assembly of gold nanorods

P.R. Selvakannan, Eddy Dumas, Frédéric Dumur, Christine Péchoux, Patricia Beaunier, Arnaud Etcheberry, Francis Secheresse, Hynd Remita, Cédric Mayer

Gold nanorods synthesized by radiolysis were selectively end-functionalized by a fully conjugated thiol bearing a pendant terpyridine group; addition of ferrous ions led to the end-to-end 1D self-assembly of the nanorods. Similar results have been obtained when the preformed [(HStpy)Fe(tpySH)](2+)…

Facile synthesis of palladium nanowires by a soft templating method

Prem Siril, Anaïs Lehoux, Laurence Ramos, Patricia Beaunier, Hynd Remita

Very long and thin monocrystalline Pd nanowires were synthesized by decomposition using hydrazine vapour treatment of Pd2(DBA)3 confined in the oil phase of a hexagonal mesophase. The mesophase is composed of toluene-swollen tubes, doped with the Pd precursor, stabilized by a monolayer of…

Amphiphilic block copolymer nano-fibers via RAFT-mediated polymerization in aqueous dispersed system

Stephanie Boisse, Jutta Rieger, Khaled Belal, Aurelie Di-Cicco, Patricia Beaunier, Min-Hui Li, Bernadette Charleux

Self-assembled block copolymer nanofibers are attractive materials for multiple applications. We propose here a novel, very simple and straightforward method to prepare polymeric nanofibers at high solids contents directly in water. It is based on an aqueous emulsion polymerization process…

Fluorescent core-shell nanoparticles and nanocapsules using comb-like macromolecular RAFT agents: synthesis and functionalization thereof

Chloé Grazon, Jutta Rieger, Patricia Beaunier, Rachel Méallet-Renault, Gilles Clavier

Fluorescent nanoparticles and nanocapsules (FNPs) were synthesized via a one-pot RAFT miniemulsion process copolymerizing BODIPY-methacrylate and styrene in water. Ultra-bright sub-100 nm core–shell nanoparticles could be obtained with BODIPY covalently linked in the core, and possessing various…
