Modelling of a Lean NOx-Trap system with NO/NO2 differentiation and sulfur poisoning

Alexis Manigrasso, Pierre Darcy, Patrick da Costa

One of the challenges in the automotive industry is to develop new vehicles and new technologies with minimal costs. In this context, modeling becomes an important tool for the design of future technologies by reducing the number of tests needed to develop a new exhaust system. With the emergence…

Building of an immunosensor : how can the composition and structure of the thiol attachment layer affect the immunosensor efficiency ?

Elisabeth Briand, Michèle Salmain, Jean-Marie Herry, Hubert Perrot, Chantal Compere, Claire-Marie Pradier

Immunosensors, based on the immobilsation of model rabbit antibodies on a mixed self assembled monolyaers and Protein A as a linking agent on gold transducers, were elaborated and characterised at each step by Modulated polarisation- Infrared Spectroscopy (PM-IRRAS) and punctually by Atomic Force…

On-line inductively coupled plasma-atomic emission spectroelectrochemistry: Real-time element-resolved electrochemistry

Borhan Bin Mohamad Sultan, Oumaïma Gharbi, Kevin Ogle, Junsoo Han

Electrochemical techniques are coupled with inductively coupled plasma (ICP) atomic emission spectrometry for in-line electrolyte analyses. In this way, direct measurement of the elemental dissolution rates in real-time or element-resolved electrochemistry can be carried out, complementary to…

On the promotional effect of Pd on the propene-assisted decomposition of NO on chlorinated Ce0.68 Zr0.32 O2

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

The selective catalytic reduction (SCR) of NOx assisted by propene is investigated on Pd/Ce0.68 Zr0.32 O2 catalysts (Pd/CZ), and is compared, under identical experimental conditions, with that found on a Pd/SiO2 reference catalyst. Physico-chemical characterisation of the studied catalysts along…

In Situ Solid–Gas Reactivity of Nanoscaled Metal Borides from Molten Salt Synthesis

Guillaume Gouget, Damien P. Debecker, Ara Kim, Giorgia Olivieri, Jean-Jacques Gallet, Fabrice Bournel, Cyril Thomas, Ovidiu Ersen, Simona Moldovan, Clément Sanchez, Sophie Carenco, David Portehault

Metal borides have mostly been studied as bulk materials. The nanoscale provides new opportunities to investigate the properties of these materials, e.g., nanoscale hardening and surface reactivity. Metal borides are often considered stable solids because of their covalent character, but little is…

Methane dry reforming over hydrotalcite-derived Ni–Mg–Al mixed oxides: the influence of Ni content on catalytic activity, selectivity and stability

Radosław Dębek, Monika Motak, Dorota Duraczyska, Franck Launay, Maria Elena Galvez, Teresa Grzybek, Patrick da Costa

Ni-containing hydrotalcite-derived catalysts were prepared using different Ni loadings (from ca. 4 to 60 wt%) at the same MII/MIII ratio equal to 3. The influence of the Ni content on the physico-chemical features of these catalysts was studied, as well as the influence of this parameter on their…

Urea electro-oxidation byproducts impact on NiO/NiOOH anode performance studied by operando electrochemical impedance spectroscopy

Sophia Akkari, Vincent Vivier, Carlos M Sánchez-Sánchez

With significant quantities of urea (CO(NH2)2) being worldwide produced and its presence at high concentration in urine, simultaneous treatment of urea effluents and hydrogen production by paired electrolysis represents a very attractive approach in circular economy. Urea electro-oxidation on Ni-…
