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…

Molecular mechanism of barnacle adhesion : a structural approach and underlying biochemistry, Mécanisme moléculaire de l'adhésion des balanes : approche structurale et biochimie sous-jacente

Sunyoung Hur

Barnacles adhere themselves robustly and permanently to diverse underwater substrates through strong interactions of a multi-protein complex layer called the “cement”. However, the intermolecular interactions responsible for the strong adhesive properties of the barnacle cement remains poorly…, Les balanes adhèrent de manière robuste et permanente à divers substrats sous-marins grâce à de fortes interactions d’une couche complexe multiprotéique appelée « ciment ». Cependant, les interactions intermoléculaires responsables des fortes propriétés adhésives du ciment de bernacle restent mal…

Mechanistic Investigation of Isopropanol Conversion on Alumina Catalysts: Location of Active Sites for Alkene/Ether Production

Kim Larmier, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Johnny Abboud, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Alcohol dehydration is of prominent relevance in the context of biomass conversion. This reaction can be efficiently catalyzed by alumina surfaces, but the nature of active sites, the mechanisms involved, and the key parameters to tune both the activity and the alkene/ether selectivity remain a…

Novel insights on H2S and COS removal for gas purification applications

David Chiche, Laure Neveux, Vincent Girard, Taha Hlayhel, Karin Barthelet, Javier Pérez-Pellitero, Arnaud Baudot, Delphine Bazer-Bachi, Anne-Sophie Gay, Schweitzer Jean-Marc, Loïc Favergeon, Michèle Pijolat, Christophe Geantet, Guylene Costentin

H₂S and COS are well-known gaseous pollutants encountered in many applications. Synthetic fuels produced from thermochemical routes (Fisher-Tropsch based XTL processes) or IGCC technologies for cleaner power production are among the applications for which the removal of H<…

Influence of the postsynthesis preparation procedure on catalytic behaviour of Ag-loaded BEA zeolites in the hydrodechlorination of 1,2-dichloroethane into value added products

A. Śrębowata, R. Baran, G. Słowik, D. Lisovytskiy, Stanislaw Dzwigaj

Two silver-containing BEA zeolites prepared by a two-step postsynthesis method (Ag2.0SiBEA) and a conventional wet impregnation (Ag2.0HAlBEA) showed a high activity in the conversion of 1,2-dichloroethane (1,2-DCE) into value added products with 100% selectivity into ethylene and 100% selectivity…

Electrochemistry of a new carbon-rich fluorine-doped tin oxide (CFTO) material as a powder electrode in chloride electrolytes

Chantal Cachet, Hubert Cachet, B Jousseaume, T Toupance, Vincent Vivier

The electrochemical behavior of a conductive carbon-rich fluorine-doped tin oxide (CFTO) powder synthesized via the sol–gel process was investigated by studying the chloride oxidation reaction in aqueous media with the help of a cavity microelectrode (CME) without any binding additive. This new…

High selectivity of TaSiBEA zeolite catalysts in 1,3-butadiene production from ethanol and acetaldehyde mixture

Pavlo I. Kyriienko, Olga V. Larina, Sergiy O. Soloviev, Svitlana M. Orlyk, Stanislaw Dzwigaj

New tantalum-silica based zeolite catalysts (TaSiBEA) were applied in this work for 1,3-butadiene production from ethanol. Tantalum incorporation into vacant T-atom sites of the SiBEA zeolites framework as mononuclear Ta(V) allowed preparing highly selective catalysts for ethanol/acetaldehyde…
