Using the technique of Cs+ reactive ion scattering (Cs+ RIS), we show
that reaction of CO and O on a Pt(111) surface produces a CO2 precursor
species that remains stable on the surface up to 300 K. The CO2 species
desorbs with an activation energy of 46�3 kJ mol�1, whereas the direct
CO2 gas formation via Langmuir�Hinshelwood (LH) reaction between
CO and O occurs with an activation energy of 75�4 kJ mol�1. The observation
reveals a new pathway for CO oxidation reaction, which is different
from the direct LH pathway.
