Detailed kinetic modeling study of NOx oxidation and storage and their interactions over Pt/Ba/Al2O3 monolith catalysts

Nikola Rankovic, Andre Nicolle, Patrick da Costa

The concept of nitrogen oxide storage-redn. (NSR) is a promising aftertreatment technol. for reducing NOx emissions from lean-burn engine exhaust. The present work focuses on the first two steps of the overall NSR mechanism, namely, NO to NO2 oxidn. and NOx storage. The governing storage mechanisms…

Non-Hydroxyl Radical Species Production during Dark Air Oxidation of Alluvial Soils

Elora Bourbon, Frédéric Averseng, Pierre Le Pape, Thierry Allard, Fulvia Baratelli, Fabrice Alliot, Alexandre Gélabert, Valentine Rollot, Elodie Guigon, Jessica Brest, Sylvie Nélieu, Guillaume Morin

Natural environments subjected to hydrologically-driven redox fluctuations are regarded as propitious to contaminant degradation since they favor cyclic oxygenation of Fe(II)-minerals that produces oxidizing reactive species, such as the hydroxyl radical, OH • . However, the identity of these…

Controlling the Nucleation of a Semicrystalline Polymer by Inducing Compartmentalization of Competitive Nucleating Agents

Arnaud Y.‐g. Delplanque, Sandra Casale, Bruno Bresson, Paolo Edera, Clément Guibert, Nathan J van Zee

Many functional polymeric systems have been inspired by the principle of compartmentalization, a ubiquitous form of hierarchical assembly found in Nature. For instance, polymers have been elaborated with microcapsules that release a chemical payload upon activation by an external stimulus. A…

Impact of sorbitol addition on the structure and performance of silica-supported cobalt catalysts for Fischer-Tropsch synthesis

Hong Jingping, Eric Marceau, Andrei Y. Khodakov, Anne Griboval-Constant, Camille La Fontaine, Françoise Villain, Valérie Briois, P.A. Chernavskii

The paper focuses on the impact of sorbitol addition on the genesis of cobalt active phases in silica-supported catalysts and on their performance in Fischer-Tropsch synthesis. The catalysts were characterized by ex situ and in situ diffuse reflectance spectroscopy in the ultraviolet and visible…

Influence of the texturalproperties of porousaluminas on the reducibility of Ni/Al2O3 catalysts

Faiza Bentaleb, Eric Marceau

Temperature-programmed reduction (TPR) profiles recorded on calcined Ni/Al2O3 catalysts exhibiting the same Ni(II) surface density (3 Ni2+ nm−2) suggest that nickel speciation and reducibility are significantly influenced by the specific surface area and texturalproperties of aluminas, and by their…

CO 2 methanation over LDH derived NiMgAl and NiMgAlFe oxides: Improving activity at lower temperatures via an ultrasound-assisted preparation

Michel Obeid, Christophe Poupin, Madona Labaki, Samer Aouad, Sharad Gupta, Haingomalala Lucette Tidahy, Aida Younis, Ferdaous Ben Romdhane, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad, François Delattre

Within the idea to catalyze CO 2 methanation NiMgAl and NiMgAlFe oxides were synthesized by the layered double hydroxide route using co-precipitation and ultrasound-assisted co-precipitation. MgAl and MgAlFe oxides-supported Ni materials prepared by the impregnation method were used as references.…

Hybrid Hydrophobin/Gold Nanoparticles: Synthesis and Characterization of New Synthetic Probes for Biological Applications

Jane Politi, Luca de Stefano, Paola Giardina, Sandra Casale, Ilaria Rea, Jolanda Spadavecchia

We report a simple and original method to synthesize gold nanoparticles in which a fungal protein, the hydrophobin Vmh2 from Pleurotus ostreatus, mixed to cetyltetrammonium bromide (CTAB) has been used as additional component in a one-step synthesis, leading to shell-like hybrid protein-metal…
