2_12/2010Cover Picture: Platinum-Like Catalytic Behavior of Au+ (ChemCatChem 12/2010)

The cover picture shows the dramatic change in the catalytic activity of supported metallic gold nanoparticles brought about by their treatment with cyanide solution. In their Full Paper on p. 1582 ff., Oyama et al. describe how this treatment does not result in dissolution of the nanoparticles, as previously thought, but in their reprecipitation as gold cyanide particles. When this happens, their catalytic activity changes from oxidation to reduction. Thus, the product of the reaction between propylene and H2/O2 mixtures shifts from propylene oxide to propane. In this manner, oxidized gold acquires the catalytic properties of platinum, its neighbor in the periodic table.
