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…

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…

Thermal and structural stability of microporous natural clinoptilolite zeolite

Radovan Kukobat, Ranko Škrbić, Pascale Massiani, Karima Baghdad, Franck Launay, Maria Sarno, Claudia Cirillo, Adolfo Senatore, Esad Salčin, Suzana Gotovac Atlagić

Thermal treatment of zeolites prior to their use as adsorbents is needed to remove adsorbed water from zeolite pores, increasing porosity and surface area without inducing structural deterioration. Here, natural zeolite clinoptilolite (CLI) was thermally treated at 378–1073 K in air atmosphere.…

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…

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…

Site-specific grafting on titanium surfaces with hybrid temporin antibacterial peptides

Nicolas Masurier, Jean-Baptiste Tissot, Douae Boukhriss, Said Jebors, Coline Pinese, Pascal Verdié, Muriel Amblard, Ahmad Mehdi, Jean Martinez, Vincent Humblot, Gilles Subra

Relying on a membrane-disturbing mechanism of action and not on any intracellular target, antimicrobial peptides (AMP) are attractive compounds to be grafted on the surface of implantable materials such as silicone catheters or titanium surgical implants. AMP sequences often display numerous…

“Water soluble” palladium nanoparticle engineering for C–C coupling, reduction and cyclization catalysis

A. Iben Ayad, C. Belda Marín, E. Colaco, C. Lefevre, C. Methivier, A. Ould Driss, J. Landoulsi, Erwann Guénin

The use of Pd nanoparticles (Pd-NPs) to realize several important organic reactions allows efficient catalysis with low metal loading (<1000 ppm), hence providing a greener catalytic system. However, to be truly green Pd-NPs need to be synthesized in a sustainable manner and be able to react…

Fischer-Tropsch reaction on Co-containing microporous and mesoporous Beta zeolite catalysts: the effect of porous size and acidity

Renata Sadek, Karolina Chalupka, Pawel Mierczynski, Jacek Rynkowski, Yannick Millot, Laetitia Valentin, Sandra Casale, Stanislaw Dzwigaj

This work deals with the investigation of the influence of the preparation procedure on the activity of microporous and mesoporous CoBeta zeolite in Fischer – Tropsch synthesis (FTS). The series of CoSiBeta, CoAlSiBeta and CoAlBeta zeolites were prepared by: i) two-step postsynthesis procedure (…
