Cover Story:

The deposition of platinum on the surface of nanosized Mn2O3 having cubic symmetry leads to the formation of finely divided PtO and Pt(OH)2. The CO adsorption in an inert atmosphere or in the presence of oxygen leads to a partial reduction in the Pt2+ surface species and the formation of linear Pt1+−CO and Pt0−CO carbonyls.

Based on the combination of experimental results and model calculations, it is concluded that the Mars–van Krevelen mechanism is the most probable over pure Mn2O3. The addition of platinum to Mn2O3 changes the reaction mechanism to the Langmuir–Hinshelwood type. Both linear carbonyls, formed on Pt1+ and Pt0 centers, took part in the reaction on the surface of Pt/Mn2O3. View this paper
