Abstract :
We present evidence that adsorption probabilities (gas–surface adsorption dynamics) of CO depend distinctly on the Au cluster size, with a reactivity maximum at ∼3 nm. This cluster size is consistent with the legendary reactivity enhancement seen for the CO-oxidation reaction. Electron beam lithography has been used to fabricate some of the samples (down to 12 nm) as well as physical vapor deposition.
