Synthesis of metal oxide catalysts

Xavier Carrier, Sébastien Royer, E. Marceau

This chapter gives an overview of the current preparation strategies for the synthesis of bulk and supported metal oxide catalysts, in order to give rational guides to understand the synthetic challenges associated with the preparation of these catalytic systems developed in the successive chapters…

Palladium Nanowires Synthesized in Hexagonal Mesophases: Application in Ethanol Electrooxidation

Faygal Ksar, Geetarani Surendran, Laurence Ramos, Bineta Keita, Louis Nadjo, Eric Prouzet, Patricia Beaunier, Agnes Hagege, Fabrice Audonnet, Hynd Remita

Palladium nanowires (of length a few tens of nanometers) are synthesized in a hexagonal mesophase formed by a quaternary system (Pd-doped water, surfactant, cosurfactant, and oil) by electron beam irradiation. The mesophases can be doped by high concentrations of palladium (0.1 M) without any…

Selective Oxidation of Methane to Formaldehyde Catalyzed by Phosphates: Kinetic Description by Bond Strengths and Specific Total Acidities

Vasilij Gomonaj, Hervé Toulhoat

A kinetic model predicts the experimental activity and selectivity patterns obtained in oxidation of methane for divided unsupported orthophosphates (M II 3(PO4)2, M III PO4,) and pyrophosphates (M II 2P2O7, M IV P2O7) catalysts spanning extended ranges of M-O bond strength (calculated from first…

Surface-induced assembly of sophorolipids

Jessie Peyre, Ahmed Hamraoui, Marco Faustini, Vincent Humblot, Niki Baccile

The surface self-assembly properties of acidic sophorolipids, a bolaform microbial glycolipids with pH-responsive properties in solution, were studied based on the chemical nature of the support and pH of the solution. Sophorolipids generally form micelles in water but formation of morphologies…

Adsorption and thermal condensation mechanisms of amino acids on oxide supports : I. Glycine on silica

Ming Meng, Lorenzo Stievano, Jean-François Lambert

Glycine was adsorbed on the surface of a well-defined silica from aqueous solutions of variable concentrations and pHs. The adsorbed molecules were characterized using middle-IR and UV-vis-NIR spectroscopies. Except at the lowestpH(2.0), they were predominantly present on the surface as zwitterions…

Effect of Coverage and Defects on the Adsorption of Propanethiol on Au(111) Surface: A Theoretical Study

Noelia B. Luque, Elizabeth Santos, Juan Andres, Frederik Tielens

Periodic density functional calculations have been carried out to investigate both the thiol adsorption on Au(111) surface and the reaction mechanism for the formation of the self-assembled monolayers, taking propanethiol as a representative example. The effect of coverage and surface defects (…

Emergence of Order in Origin-of-Life Scenarios on Mineral Surfaces: Polyglycine Chains on Silica

Ola El Samrout, Marco Fabbiani, Gloria Berlier, Jean-François Lambert, Gianmario Martra

The polymerization of amino acids (AAs) to peptides on oxide surfaces has attracted interest owing to its high importance in biotechnology, prebiotic chemistry, and origin of life theories. However, its mechanism is still poorly understood. We tried to elucidate the reactivity of glycine (Gly) from…
