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…

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…

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…

Immobilization of polyoxometalate hybrid catalysts onto mesoporous silica supports using phenylene diisothiocyanate as a cross-linking agent

Ourania Makrygenni, Dalil Brouri, Anna Proust, Franck Launay, Richard Villanneau

The hybrid derivative of heteropolytungstate bearing two aniline groups, namely (nBu4N)3[NaHPW9O34{As(O)C6H4NH2}2], was post-functionalized in the presence of 1,4-phenylene diisothiocyanate (PDITC). The resulting molecular moiety was characterized by IR, 1H and 31P NMR spectroscopy. In a second…

Binding mechanism of oligopeptides on solid surface: assessing the significance of single-molecule approach

Joanne Lê-Chesnais, Marie Steffenhagen, Christophe Méthivier, Dominique Costa, Daniela Rodriguez, Jean-François Lambert, Emmanuel Maisonhaute, Jessem Landoulsi

This paper addresses the complementarity and potential disparities between single-molecule and ensemble-average approaches to probe the binding mechanism of oligopeptides on inorganic solids. Specifically, we explore the peptide/gold interface owing to its significance in various topics and its…

Naked Eye Immunosensing of Food Biotoxins Using Gold Nanoparticle-Antibody Bioconjugates

Lu Zhang, Michèle Salmain, Bo Liedberg, Souhir Boujday

Colorimetric immunoassays using gold nanoparticles (AuNP) form a special class of assays where AuNP act as a transducer to monitor binding events between an antigen and an antibody. Indeed, AuNP display unique optical properties that can been exploited in various ways to develop biosensors. One of…

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…
