概要 We have studied the local properties of single Pt atoms adsorbed on hydroxylated TiO2(110)-(1 × 1) by
combining noncontact atomic force microscopy (nc-AFM) and first-principles calculations. Room-temperature
high-resolution nc-AFM images for the most frequently observed contrast modes reveal bright and elongated
protrusions that can be traced back to the Pt atoms, and that are centered on the fivefold coordinated titanium
rows, confined between two bridging oxygen rows. These observations are in line with the theoretical results, as
the lowest energy sites for the Pt atom on the TiO2(110) surface are in the neighborhood of the titanium rows,
and high energy barriers have to be overcome to displace the Pt atom over the bridging oxygen rows.
