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…

This thesis reports on the adsorption of two amino acids (AA) with different properties, Leucine and Glutamic acid, on the amorphous silica surface. It exemplifies a general approach to hybrid systems that combines experimental information and molecular modeling in order to characterize at the…, Cette thèse porte sur l'adsorption de deux acides aminés aux propriétés différentes, la leucine et l'acide glutamique, sur la surface de la silice amorphe. Une combinaison d'informations expérimentales et de modélisation moléculaire a été entreprise afin de caractériser au niveau…

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…

The Impact of Reduction Temperature and Nanoparticles Size on the Catalytic Activity of Cobalt-Containing BEA Zeolite in Fischer–Tropsch Synthesis

Karolina A Chalupka, Jacek Grams, Pawel Mierczynski, Malgorzata I Szynkowska, Jacek Rynkowski, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A goal of this work was to investigate the influence of the preparation procedure and activation conditions (reduction temperature and reducing medium: pure hydrogen (100% H 2) or hydrogen-argon mixture (5% H 2-95% Ar)) on the activity of Co-containing BEA zeolites in Fischer-Tropsch synthesis.…

Tunable hierarchical porous silica materials using hydrothermal sedimentation-aggregation technique

Abdelali Zaki, Jing Xu, Grégory Stoclet, Sandra Casale, Jean-Philippe Dacquin, Pascal Granger

Herein, a simple and efficient synthesis based on a dual templating approach allow the preparation of tunable macroporous mesoporous silica materials. Macropores incorporation has been obtained using polymer spheres of well-defined size and their subsequent removal by thermal treatment allowed the…

Steam reforming of alpha-methylnaphthalene as a model tar compound over olivine and olivine supported nickel

Rudy Michel, Agata Lamacz, Andrzej Krzton, Gérald Djéga-Mariadassou, Philippe Burg, Claire Courson, Rene Gruber

At high temperature, biomass steam gasification generates tars and more particularly Polycyclic Aromatic Hydrocarbons (PAHs). To assess the ability of olivine-based catalyst to eliminate the tars by steam reforming, alpha-methylnaphthalene (MNP) was chosen as model compound. The Ni/olivine has…

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.…
