The Synthesis of Different Series of Cobalt BEA Zeolite Catalysts by Post-Synthesis Methods and Their Characterization

Renata Sadek, Karolina Chalupka-Spiewak, Jean-Marc Krafft, Yannick Millot, Laetitia Valentin, Sandra Casale, Jacek Gurgul, Stanislaw Dzwigaj

Three series of zeolite catalysts Co all-silica and Co Al-containing zeolites beta were prepared for use in the selective oxidative dehydrogenation of propane to propylene. Two series of zeolite catalysts Co all-silica were prepared by a two-step postsynthesis method at pH = 2.5 and pH = 3.0-9.0,…

Does the S-H Bond Always Break after Adsorption of an Alkylthiol on Au(111)?

Hazar Guesmi, Noelia B. Luque, Elizabeth Santos, Frederik Tielens

The reaction mechanism for the formation of alkyl thiol self-assembled monolayers (SAM) on Au(111) is still not clearly understood. Especially, the role of defects on the chemisorption process is an important goal to be addressed. In this work, different minimum energy reaction paths for R−SH…

Synthesis of small Ni-core–Au-shell catalytic nanoparticles on TiO2 by galvanic replacement reaction

Julien Reboul, Z. y Li, Jun Yuan, Kazuki Nakatsuka, Masakazu Saito, Kohsuke Mori, Hiromi Yamashita, Yu Xia, Catherine Louis

We report the first preparation of small gold–nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this…

Preparation of Pt°/MCM-41: effect of drying on MCM-41 structure and Pt° dispersion

Baichun Zhu, Franck Letellier, Juliette Blanchard, Katia Fajerwerg, Catherine Louis, Denis Guillaume, Denis Uzio, Miehèle Breysse

Pt°/MCM-41 catalysts were prepared by electrostatic adsorption of Pt(NH3)42+ at pH=8, followed by calcination under O2 and reduction. This procedure allows to prepare highly dispersed Pt° nanoparticles (D>76%), but has the drawback to modify significantly the structure of the ordered mesoporous…

Scanning Electrochemical Microscopy for Investigating Gas Bubble/Liquid Interfaces

Claude Gabrielli, François Huet, Michel Keddam, Philippe Rousseau, Vincent Vivier

Scanning electrochemical microscopy was used to characterize air bubble/electrolyte interfaces for bubbles of diameter in the millimeter range. Contrary to rigid insulated substrate/liquid interfaces, the approach of the tip of the microelectrode was shown to lead to a deformation of the bubble…

Experimental clues for detecting biosignatures on Mars

J.-C. Viennet, S. Bernard, Corentin Le Guillou, P. Jacquemot, E. Balan, L. Delbes, B. Rigaud, T. Georgelin, M. Jaber

Forthcoming exploration of Mars aims at identifying fossil biosignatures within ancient clay-rich formations. The subsurface of Mars has mostly acted as a giant freezer for the last 4 Gyr, thereby preserving potential remains of martian life. Yet, volcanism and impactors have periodically triggered…
