Non-thermal plasma assisted catalytic NOx remediation from a lean model exhaust

Olivier Gorce, Hervé Jurado, Cyril Thomas, Gérald Dega-Mariadassou, Ahmed Khacef, Jean Marie Cormier, Jean Michel Pouvesle, Gérard Blanchard, Sabine Calvo, Yvanne Lendresse

No efficient catalyst presently exists for deNOx in lean burn conditions. Furthermore, actual catalysts generally deactivate during reaction. A cylindrical DBD non-thermal plasma reactor was coupled with a stable three-function catalyst in order to verify the nature of the effect of the plasma on…

Sulfur Deactivation of NOx Storage Catalysts: A Multiscale Modeling Approach.

Nikola Rankovic, Céline Chizallet, Andre Nicolle, David Berthout, Patrick da Costa

Lean NOx Trap (LNT) catalysts, a promising solution for reducing the noxious nitrogen oxide emissions from the lean burn and Diesel engines, are technologically limited by the presence of sulfur in the exhaust gas stream. Sulfur stemming from both fuels and lubricating oils is oxidized during the…

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…

Selective Oxidation of Methane to Formaldehyde Catalyzed by Phosphates: Kinetic Description by Bond Strengths and Specific Total Acidities

Vasilij Gomonaj, Hervé Toulhoat

A kinetic model predicts the experimental activity and selectivity patterns obtained in oxidation of methane for divided unsupported orthophosphates (M II 3(PO4)2, M III PO4,) and pyrophosphates (M II 2P2O7, M IV P2O7) catalysts spanning extended ranges of M-O bond strength (calculated from first…

Cobalt Based Catalysts Supported on Two Kinds of Beta Zeolite for Application in Fischer-Tropsch Synthesis

Renata Sadek, Karolina Chalupka, Pawel Mierczynski, Jacek Rynkowski, Jacek Gurgul, Stanislaw Dzwigaj

Co-containing Beta zeolite catalysts prepared by a wet impregnation and two-step postsynthesis method were investigated. The activity of the catalysts was examined in Fischer-Tropsch synthesis (FTS), performed at 30 atm and 260 °C. The physicochemical properties of all systems were investigated by…

Nanostructured and spiky gold in biomolecule detection: improving binding efficiencies and enhancing optical signals

E. E. Bedford, S. Boujday, C.-M. Pradier, F. X. Gu

Nanostructured gold can improve the ability to detect biomolecules. Whether planar nanostructured surfaces or nanostructured particles are used, similar principles governing the enhancement apply. The two main benefits of nanostructured gold are improved geometry and enhancement of optical…

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…
