Abstract
Reactions of CO and O2 on size-selected copper cluster anions, Cu n - (n = 4–11), have been investigated at the collision energy of 0.2 eV by use of a guided ion beam-tandem mass spectrometer. Oxygen-adsorbed copper anions, Cu n O2 -, in particular Cu5O2 - and Cu9O2 -, show an evidence of the CO oxidation, that is, the formation of the monoxide Cu n O−. The density functional theory calculation reveals that the CO oxidation occurs more exothermically on Cu5O2 - and Cu9O2 - than the other clusters. This can be explained by the relatively small dissociation energy of their Cu–O bonds. In addition, the calculations on Cu5O2 +/- indicate that the CO oxidation proceeds via a low-energy pathway for the anion owing to the structural rearrangement of the copper cluster compared to the cation.
