Titel:
Tuning the oxidation of carbon monoxide using nanoassembled model catalysts 
Abstract:
While the oxidn. of CO has long been considered to be structure insensitive, nano-assembled model catalysts consisting of size-selected metal clusters (Aun, Ptn, Pdn, and Rhn, n=1-20), supported on thin MgO(1 0 0) films, reveal distinct size-effects. When adding a single Pt atom to Pt14, platinum clusters increase their reactivity by a factor of three. Rh20 shows the highest reactivity of all the investigated clusters, oxidizing about 13 CO mols. per cluster at 350 K. While F-centers on MgO film...    »
