As SO, is a major atmospheric pollutant coming mainly from combustion and is also a reactant involved in reaction on catalysts, it is therefore of interest to undertake studies on the initial interaction of SO, with surfaces of metallic materials. In

The first steps of H 2 S adsorption have been studied on polycrystalline copper samples, which are more relevant to industrial copper samples than to single-crystal surfaces. The tools for characterization are ultrahigh vacuum spectroscopic methods,

In the presence of mixed copper-chromium (aluminium) oxide, allylic alcohols react with molecular hydrogen and lead to several primary products. This is due to the simultaneous presence of two active sites in the mixed oxides. Copper species (Cu+) ar

A cubic phase close to that of γCr 2 O 3 has been observed in copper chromite catalysts with atomic ratio 0,8 ⩽ Cu/Cr ⩽ 1,5. The infra-red spectroscopy shows that Cr 6+ ions should be necessary for the stability of the phase. Cr 3+ ions in tetra
