Abstract

Mass-selected Au clusters consisting of less than 10 atoms were deposited on sputter-damaged HOPG surfaces. Oxidation and reduction of the Au clusters were studied using X-ray photoelectron spectroscopy. Only Au₈ can be significantly oxidized by oxygen and reduced by CO, and the result is different from those for Au clusters deposited on silica. The chemical properties of mass-selected clusters are dissimilar to those of Au nanoparticles larger ∼2-3 nm. STM studies on Au₇ suggest that Au₇ exists as individual clusters rather than forming larger particles on the surface.
