The state of BEA zeolite supported nickel catalysts in CO2 methanation reaction

Wojciech Gac, Witold Zawadzki, Grzegorz Słowik, Marcin Kuśmierz, Stanislaw Dzwigaj

Two model nickel catalysts for CO2 methanation reaction were prepared by the impregnation method using unmodified and dealuminated BEA-type zeolite supports, denoted NiHAlBEA and NiSiBEA. Transmission electron microscopy (TEM) and X-ray diffraction studies evidenced formation of metallic nickel…

Unraveling the Direct Decomposition of NO x over Keggin Heteropolyacids and Their Deactivation Using a Combination of Gas-IR/MS and In Situ DRIFT Spectroscopy

Josefine Schnee, Laurent Delannoy, Guylène Costentin, Cyril Thomas

Keggin heteropolyacids (HPAs) have been known to be efficient NOx absorbers for many years, and to decompose a significant fraction of the NOx species pre-absorbed at 100-150 °C into harmless N2 and O2 upon rapid heating to 450 °C. However, this capability of Keggin HPAs to directly decompose NOx…

Generation of pits on CoCrFeMnNi high entropy alloy: an electrochemical impedance study of a single event

Yaojun Hou, Oumaïma Gharbi, Kevin Ogle, Fan Sun, Mireille Turmine, Vincent Vivier

In this study, a single pit was successfully generated on the surface of a CoCrFeMnNi alloy using a home-made device consisting of an electrochemical work station coupled with a microflow-cell. The three-dimensional morphology of the single pit was observed by optical microscopy, revealing that the…

Optimizing the immobilization of gold nanoparticles on functionalized silicon surfaces: amine- vs thiol-terminated silane

Maroua Ben Haddada, Juliette Blanchard, Sandra Casale, Jean-Marc Krafft, Anne Vallée, Christophe Méthivier, Souhir Boujday

Immobilization of gold nanoparticles on planar surfaces is of great interest to many scientific communities; chemists, physicists, biologists, and the various communities working at the interfaces between these disciplines. Controlling the immobilization step, especially nanoparticles dispersion…

Chemical Differentiation of Planets: A Core Issue

Hervé Toulhoat, Viacheslav Zgonnik

By plotting empirical chemical element abundances on Earth relative to the Sun and normalized to silicon versus their first ionization potentials, we confirm the existence of a correlation reported earlier. To explain this, we develop a model based on principles of statistical physics that predicts…

Développement de biocathodes pour biopiles enzymatiques utilisant la laccase, Development of an enzymatic cathode biofuel cell using laccase

Mohamed Achraf Blout

Les biopiles enzymatiques constituent une alternative intéressante de production d'électricité renouvelable. On s'est intéressé dans ce travail au compartiment cathodique d'une biopile utilisant la laccase, une oxydase multi-cuivres, comme biocatalyseur pour la réduction de l'…, Enzymatic biofuel cells are an attractive alternative for renewable electricity generation. In this work, we are focusing on the cathodic compartment of a biofuel cell using laccase, a multi-copper oxidase, as biocatalysts for the oxygen reduction reaction (ORR) by direct electron transfer of…

Surface segregation in AuPd alloys: Ab initio analysis of the driving forces

Jérôme Creuze, Hazar Guesmi, Christine Mottet, Beien Zhu, Bernard Legrand

In order to determine the energetic driving forces for surface segregation in AuPd alloys, we use a combined approach coupling ab initio calculations and an analysis via an effective Ising model. Previously, this approach has been used successfully in the framework of N-body interatomic potentials…
