It depends on O: The catalytic properties of ultrathin oxide films are studied by using the low‐temperature oxidation of CO as a benchmark reaction. The results reveal a strong correlation between the activity and the desorption energy of the most weakly bound oxygen species present on these films under net oxidizing conditions at near‐atmospheric pressures. The results suggest the use of oxygen binding energy as a suitable descriptor for the reaction.
