Zn-Cu Alloy Nanofoams as Efficient Catalysts for the Reduction of CO 2 to Syngas Mixtures with a Potential-Independent H 2 /CO Ratio

Sarah Lamaison, David Wakerley, David Montero, Gwenaëlle Rousse, Dario Taverna, Domitille Giaume, Dimitri Mercier, Juliette Blanchard, Huan Ngoc Tran, Marc Fontecave, Marc Mougel

Alloying strategies are commonly used to design electrocatalysts that take on properties of their constituent elements. Herein, we explore the use of such a strategy to develop Zn-Cu alloyed electrodes with unique hierarchical porosity and tunable selectivity for CO2 vs. H + reduction. By varying…

Fischer carbene mediated covalent grafting of a peptide nucleic acid on gold surfaces and IR optical detection of DNA hybridization with a transition metalcarbonyl label

Pratima Srivastava, Mahsa Ghasemi, Namrata Ray, Amitabha Sarkar, Jana Kocabova, Stepanka Lachmanova, Magdalena Hromadova, Souhir Boujday, Silvia Cauteruccio, Emanuela Licandro, Pramod Thakare, Céline Fosse, Michèle Salmain

Amine-reactive surfaces comprising N-hydroxysuccinimide ester groups as well as much more unusual Fischer alkoxymetallocarbene groups were generated on gold-coated surfaces via self-assembled monolayers of carboxy- and azido-terminated thiolates, respectively. These functions were further used to…

Gold Nanoparticles Assembly on Silicon and Gold Surfaces: Mechanism, Stability and Efficiency in Diclofenac Biosensing

Maroua Ben Haddada, Maria Hübner, Sandra Casale, Dietmar Knopp, Reinhard Niessner, Michele Salmain, Souhir Boujday

We investigated the assembly of Gold nanoparticles (AuNPs) on Gold and Silicon sensors with two final objectives: (i) understanding the factors governing the interaction and (ii) building up a nanostructured piezoelectric immunosensor for diclofenac, a small-sized pharmaceutical pollutant.…

Heteropolytungstate-decorated core-shell magnetic nanoparticles: A covalent strategy for polyoxometalate-based hybrid nanomaterials

Ourania Makrygenni, Emilie Secret, Aude Michel, Dalil Brouri, Vincent Dupuis, Anna Proust, Jean-Michel Siaugue, Richard Villanneau

Amino-functionalized core-shell magnetic nanoparticles have been covalently grafted with Polyoxometalates (POMs). These multifunctional nanocomposites have been obtained through the coupling of heteropolytungstate-based hybrids bearing carboxylic acid functions with aminopropyl functions that…

In Situ Cobalt Speciation on γ-Al 2 O 3 in the Presence of Carboxylate Ligands in Supported Catalyst Preparation

A. Davantès, C. Schlaup, X. Carrier, Mickael Rivallan, G. Lefèvre

Molecular-scale understanding of metal impregnation on a porous oxide support is a key step toward the development of optimized (and cost ,effective) catalytic materials with enhanced activity, selectivity and time on stream stability. In the present contribution in situ ATR-IR and ex situ…

Hierarchical Self-Assembly of Polyoxometalate-Based Hybrids Driven by Metal Coordination and Electrostatic Interactions: From Discrete Supramolecular Species to Dense Monodisperse Nanoparticles

Guillaume Izzet, Benjamin Abécassis, Dalil Brouri, Madeleine Piot, Benjamin Matt, Stefano Artin Serapian, Carles Bo, Anna Proust

The metal-driven self-assembly processes of a covalent polyoxometalate (POM)-based hybrid bearing remote terpyridine binding sites have been investigated. In a strongly dissociating solvent, a discrete metallomacrocycle, described as a molecular triangle, is formed and characterized by 2D diffusion…

Self-Assembling of Redox-Active Atrazine Poly(ethylenimine) Conjugates – Interfacial Electrochemical and Spectroscopic Characterization

Zhaohui Chen, Michèle Salmain, Claire-Marie Pradier, Nathalie Fischer-Durand, Alain Pailleret, Féthi Bedioui, Sandrine Zanna

Thin films of polymers tethered with both atrazine haptens and ferrocenyl (Fc) probes were formed on polycrystalline gold electrodes by taking advantage of the facile formation of self-assembled monolayers (SAMs) of thiolates. These films were characterized by polarization modulation Fourier…
