HRTEM and STEM-HAADF characterisation of Au-TiO2 and Au-Al2O3 catalysts for a better understanding of the parameters influencing their properties in CO oxidation

L. Delannoy, R.L. Chantry, S. Casale, Z.Y. Li, Yves Borensztein, C. Louis

Gold catalysts supported on titania (Au-TiO2) and alumina (Au-Al2O3) were prepared by deposition- precipitation with urea and then activated before characterisation and reaction in CO oxidation, either by calcination in air at 500 1C or reduction under H2 at 300 1C. Gold nanoparticles with average…

Effects of organic and inorganic treatment agents on the formation of conversion layer on hot-dip galvanized steel: An X-ray photoelectron spectroscopy study

S. Le Manchet, D. Verchere, Jessem Landoulsi

The formation of a Cr-free conversion layer on hot-dip galvanized (HDG) steel involves various interfacial processes which radically influence the composition of the coating and thus its performance. Here, we investigate the role of the main constituents contained in the treatment bath, the…

A combined EXAFS and DFT study of the Ni2+ environment in dehydrated Ni/NaX

Hazar Guesmi, Pascale Massiani

The location of the divalent nickel cation exchanged in low amount in dehydrated NaX is identified by a combination of experimental (XAS) and theoretical (DFT) approaches. The Ni-O and Ni-T distances as well as the coordination numbers evaluated from experiments are in good agreement with the…
