Heterogeneous catalytic partial oxidation of lower alkanes (C 1 –C 6 ) on mixed metal oxides

Jacques Védrine

This review paper aims at analysing the state of the art for partial oxidation and oxidative dehydrogenation (ODH) reactions of lower alkanes C1–C6 into olefins and oxygenated products (aldehydes, anhydrides, carboxylic acids) on metal oxide catalysts with cations of variable oxidation state, such…

Synthèse prébiotique de Ribonucléotides sur des surfaces minérales, Prebiotic synthesis of Ribonucleotides on mineral surfaces

Mariame Akouche

Dans le contexte prébiotique du " monde ARN ", les ribonucléotides sont considérés comme étant les premières espèces à avoir émergé sur Terre. En milieu aqueux, leur formation est défavorable thermodynamiquement. Les voies de synthèse de nucléotides décrites en phase homogène impliquent l…, In the « RNA world» prebiotic scenario, ribonucleotide polymers are considered as the first biochemical species to have emerged. However, in aqueous solution, their formation through conventional mechanisms of condensation is thermodynamically forbidden. Several synthesis pathways of nucleotides…

Oxidation and Surface Segregation Behavior of a Pt–Pd–Rh Alloy Catalyst

Paul A. J. Bagot, Karen Kruska, Daniel Haley, Xavier Carrier, Eric Marceau, Michael. P. Moody, George D. W. Smith

Platinum gauze catalysts are used extensively in the production of nitricacid from ammonia, where they are subject to harsh operating conditions combiningelevated temperatures and oxidizing environments. These cause significant loss of metalspecies as volatile oxides. How different metallic species…

Self-Assembly of (S)-Glutamic Acid on Ag(100): A Combined LT-STM and Ab Initio Investigation

M. Smerieri, L. Vattuone, Dominique Costa, Frederik Tielens, L. Savio

Self-assembly of org. mols. at metal surfaces is of greatest importance in nanoscience; in fact, it opens new perspectives in the field of mol. electronics and in the study of biocompatible materials. Combining an exptl. low-temp. scanning tunneling microscopy investigation with ab initio calcns.,…

NOx-TPD as a Tool to Estimate the Accessible Zirconia Surface of ZrO2-Containing Materials

Hiu Ying Law, Juliette Blanchard, Xavier Carrier, Cyril Thomas

NOx adsorption-desorption experiments were carried out on a series of W-free and W-containing ZrO2 samples. To the best of our knowledge, this study establishes for the first time NOx-TPD (temperature-programmed desorption of NOx) as a reliable method to estimate the accessible ZrO2 surface of…

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…

Supported gold catalysts for the decomposition of VOC: Total oxidation of propene in low concentration as model reaction

Laurent Delannoy, Katia Fajerwerg, Pandian Lakshmanan, Claude Potvin, Christophe Methivier, Catherine Louis

Supported gold catalysts prepared by deposition-precipitation with urea were studied in the reaction of oxidation of propene in low concentration in a large excess of oxygen, so as to mimic the conditions of catalytic decomposition of a volatile organic compound of hydrocarbon-type (1200 ppm C3H6,…

Amphiphilic Polyoxometalates for the Controlled Synthesis of Hybrid Polystyrene Particles with Surface Reactivity

Jennifer Lesage de la haye, Jean-Michel Guigner, Eric Marceau, Laurent Ruhlmann, Bernold Hasenknopf, Emmanuel Lacôte, Jutta Rieger

Amphiphilic organo-polyoxometalates (POMs) used in the radical emulsion polymerization of styrene allowed the preparation in aqueous medium of stable 50-100 nm polystyrene-POM composite latexes. Thanks to the presence of a trithiocarbonate group in the POM amphiphile, POMs could be covalently…

Dealuminated Beta Zeolite Modified by Alkaline Earth Metals

Karolina Chalupka, Renata Sadek, Laetitia Valentin, Yannick Millot, Christophe Calers, Magdalena Nowosielska, Jacek Rynkowski, Stanislaw Dzwigaj

Alkaline Earth metals (Mg, Sr, and Ca) were incorporated into the dealuminated mesoporous beta zeolite (DeAlBeta) by the two-step postsynthesis method. Physicochemical properties of both unmodified and alkaline Earth metal-modified DeAlBeta zeolite were characterized by XRD, DR UV-vis, FTIR, TPD of…
