Preparation of thin film gold based catalysts for oxidation reactions in liquid and gas phases

Anne-Félicie Lamic-Humblot, Philippe Barthe, Guillaume Guzman, Laurent Delannoy, Catherine Louis

This work deals with the preparation of gold on titania catalysts to make catalytic films in the less than 100 nm thickness area and its comparison with usual powder catalyst in catalytic oxidation reactions in gas and liquid phases. Titania was coated on glass plates with different thicknesses,…

Mesostructured or Alumina-mesostructured Silica SBA-16 as Potential Support for NOx Reduction and Ethanol Oxidation

Maya Boutros, Thomas Onfroy, Patrick da Costa

Synthesis of some meso-structured SiO2 or aluminosilica (SBA-16 and Al-SBA-16) with a 3-dimensional cubic structure is reported. Structural and porosity properties of these materials were studied by x-ray diffraction, N2 sorption, and transmission electron microscopy imaging.; Al insertion was detd…

Impact of sorbitol addition on the structure and performance of silica-supported cobalt catalysts for Fischer-Tropsch synthesis

Hong Jingping, Eric Marceau, Andrei Y. Khodakov, Anne Griboval-Constant, Camille La Fontaine, Françoise Villain, Valérie Briois, P.A. Chernavskii

The paper focuses on the impact of sorbitol addition on the genesis of cobalt active phases in silica-supported catalysts and on their performance in Fischer-Tropsch synthesis. The catalysts were characterized by ex situ and in situ diffuse reflectance spectroscopy in the ultraviolet and visible…

Copper incorporated mesoporous materials: synthesis, characterization and catalytic activity in benzaldehyde reduction

O. Zekri, A. Saadi, F. Launay, C. Calers, C. Rabia

Copper substituted mesoporous silica materials (Cu–HMS-n), with a variety of Si/Cu atomic ratios (n) ranging from 50 to 100, were synthesized by the one-pot sol–gel method using dodecylamine as template. These materials were characterized by X-ray diffraction, N2 adsorption-desorption, transmission…
