Chemical evolution of organic molecules under Mars-like UV radiation conditions simulated in the laboratory with the MOMIE setup

O. Poch, Patrice Coll, Cyril Szopa, F. Stalport, T. Georgelin, M. Jaber, J.F. Lambert

The search for organic carbon at the surface of Mars, as clues of past habitability or remnants of life, is a major science goal of Mars' exploration. Understanding the chemical evolution of organic molecules under current Martian environmental conditions is essential to support the past,…

Heterogeneous Partial (amm) Oxidation and Oxidative Dehydrogenation Catalysis on Mixed Metal Oxides

Jacques C. Védrine

This paper presents an overview of heterogeneous partial (amm)oxidation and oxidative dehydrogenation (ODH) of hydrocarbons. The review has been voluntarily restricted to metal oxide-type catalysts, as the partial oxidation field is very broad and the number of catalysts is quite high. The main…

Introduction of Co into the Vacant T-Atom Sites of SiBEA Zeolite as Isolated Mononuclear Co Species

Rafal Baran, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A CoSiBEA zeolite was obtained by a postsynthesis method which consisted of a treatment of tetraethylammonium BEA zeolite with nitric acid in the first step and introduction of Co ions into the vacant T atom sites of the SiBEA zeolite by reaction of aqueous Co(NO3)2 solution with silanol groups.…

Selective gas phase hydrogenation of nitroarenes over Mo 2 C-supported Au-Pd

Xiaodong Wang, Noémie Perret, Laurent Delannoy, Catherine Louis, Mark A. Keane

We report the first synthesis of Mo2C-supported Au and Au–Pd catalysts (nominal Au/Pd = 10 and 30) obtained from colloidal nanoparticles stabilised by polyvinyl alcohol (PVA). Equivalent Au/Al2O3 and Au–Pd/Al2O3 were prepared and served as benchmarks. Residual PVA was removed by thermal treatment…

Nickel Coordination to Lattice Oxygens in Basic LSX, X and Y Sodium Faujasites: A DFT Study

Hazar Guesmi, Dominique Costa, Dorothée Berthomieu, Pascale Massiani

The location and coordination of nickel cations inside the hexagonal prism of dehydrated sodium faujasites have been investigated as a function of the framework Al content and distribution by density functional theory (DFT) calculations. Three different Si/Al ratios have been considered in order to…

Synthesis and Unique Catalytic Performance of Single-Site Ti-Containing Hierarchical Macroporous Silica with Mesoporous Frameworks

Takashi Kamegawa, Norihiko Suzuki, Michel Che, Hiromi Yamashita

Single-site Ti-containing hierarchical macroporous silica with mesoporous frameworks (Ti-MMS) was successfully prepared by a solvent evaporation method using organic surfactant and poly(methyl methacrylate) (PMMA) colloidal crystals as the template. The formation of a well-defined macroporous…

Self-assembled multilayers based on native or denatured collagen: mechanism and synthesis of size-controlled nanotubes

Jessem Landoulsi, Sophie Demoustier-Champagne, Christine Dupont-Gillain

The mechanism of layer-by-layer (LbL) assembly using collagen, the major protein of the extracellular matrix, was investigated on flat substrates and in nanoporous templates, with a view to synthesize collagen-contg. nanotubes. The effect of parameters related to geometrical constraints (flat…

Chromium Oxide Species Supported on Silica: A Representative Periodic DFT Model

Hazar Guesmi, Frederik Tielens

The Cr/SiO2 system is investigated using periodic DFT. The model represents the amorphous character of the silica surface and allows the investigation of the effect of hydration on the Cr(VI) monomers. First, the geometry and energetics are discussed and compared with experimental data. The phase…
