Abstract [en]

We have used synchrotron radiation based photoelectron spectroscopy to study tin induced modifications in surface bonding of CO to Pt(111). Tin can form both so-called surface alloys, where tin replaces surface platinum atoms and ordered adatom structures where tin stays on top of the surface. The alloy is formed after annealing to 600 °C. The results from Pt(111) are in excellent agreement with previous literature, with CO binding in top site and in bridge site.

On Pt(111)-Sn alloys we observe the same species, but with a reduced bridge site emission. Tin does not take direct part in the chemical bond to CO, but it influences the nearby Pt. On the overlayer structure we observe that CO binds directly to tin. Thus we conclude that the form of tin on the surface plays an important role in the surface chemistry of CO to tin modified Pt surfaces.
