Figure 1
Left: carbon 1s photoemission spectra measured 5 min (black) and 5 h [grey (red online)] after CO dosing for 10 min in 10−8 mbar partial pressure at RT. The measurements were performed with 380 eV photon energy. The signatures of CO adsorption sites are located at BE 286.8 eV (atop) and 286.09 eV (bridge). The carbon contamination is characterized by two peaks at BE 284.0 eV and 283.6 eV. Right: oxygen 1s photoemission spectra measured with 630 eV photon energy at RT [grey (red online)] and at LN temperature [black (blue online)] after 10 min of simultaneous exposure at CO and O2 partial pressure of 0.9 × 10−8 mbar and 4.9 × 10−8 mbar, respectively. Peaks indicated by a and b are assigned to the O-1s levels of the CO molecule on different sites on Pt(111), while peak c is associated with the O-1s of the oxygen. |
