Cobalt on dealuminated-Siβ as a catalyst for the oxidative dehydrogenation of propane

Stanislaw Dzwigaj, Diane Reja, Saremblé Koné-Guira, Antoine Miche, Guylène Costentin, Cyril Thomas

The present work aims at investigating the oxidative dehydrogenation of propane (ODHP) catalytic properties of Co species supported on a Siβ zeolitic support. The Co2+ species incorporated in the silanol nests created by dealumination of a HAlSiβ pristine support (Co-Siβ) appeared to be about 4…

Synthesis of RNA nucleotides in plausible prebiotic conditions from ab initio computer simulations

Andrea Pérez-Villa, Antonino Marco Saitta, Thomas Georgelin, Jean-François Lambert, François Guyot, Marie-Christine Maurel, Fabio Pietrucci

Understanding the mechanism of spontaneous formation of ribonucleotides under realistic prebiotic conditions is a key open issue of origins-of-life research. In cells, de novo and salvage nucleotide enzymatic synthesis combines 5-phospho-α-d-ribose-1-diphosphate (α-PRPP) and nucleobases.…

Structure–Activity Relationship in Manganese Perovskite Oxide Nanocrystals from Molten Salts for Efficient Oxygen Reduction Reaction Electrocatalysis

Francisco Gonell, Carlos M Sánchez-Sánchez, Vincent Vivier, Christophe Méthivier, Christel Laberty-Robert, David Portehault

We report a synthesis pathway in molten salts toward ligand-free nanoparticles of the layered perovskite La0.5Sr1.5MnO4 (l-LSMO) and of the pseudocubic perovskite La0.7Sr0.3MnO3 (pc-LSMO). These particles are readily implemented as oxygen reduction reaction (ORR) electrocatalysts in alkaline…
