Emergence of Order in Origin-of-Life Scenarios on Mineral Surfaces: Polyglycine Chains on Silica

Ola El Samrout, Marco Fabbiani, Gloria Berlier, Jean-François Lambert, Gianmario Martra

The polymerization of amino acids (AAs) to peptides on oxide surfaces has attracted interest owing to its high importance in biotechnology, prebiotic chemistry, and origin of life theories. However, its mechanism is still poorly understood. We tried to elucidate the reactivity of glycine (Gly) from…

Ni-Silica-based Catalysts for CH4 Reforming by CO2 with Enhanced Stability: Recent Designs and the Impacts of Ni Confinement, Promoters, and Core-Shell Structures

Oscar Daoura, Maya Boutros, Franck Launay

CO2 reforming of CH4, also referred to as the Dry Reforming of Methane (DRM), is considered an excellent method to produce H2 and CO (syngas), which are known to be used for the production of higher alkanes and oxygenates. Despite nickel’s moderate toxicity, Ni-based heterogeneous catalysts are…

On the origin of the optimum loading of Ag on Al2O3 in the C3H6-SCR of NOx

Tesnim Chaieb, Laurent Delannoy, Catherine Louis, Cyril Thomas

Ag/Al2O3 catalysts synthesized by the common impregnation technique with various Ag loadings were characterized by the NOx-Temperature-Programmed Desorption (TPD) method and their catalytic performances were evaluated in the selective catalytic reduction of NOx by propene (C3H6-SCR). It was found…

Mesocellular silica foam-based Ni catalysts for dry reforming of CH4 (by CO2)

Oscar Daoura, Marie-Nour Kaydouh, Nissrine El-Hassan, Pascale Massiani, Franck Launay, Maya Boutros

Nickel-containing mesocellular silica foam (MCF) catalysts were prepared for dry reforming of methane (DRM). Different methods were used for the synthesis of the MCFs supports in order to enhance their surface areas and pore volumes. The incorporation of nickel was done by three different methods:…

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…
