These values are very close to those reported in the literature (31, 33, 34) for Mo^. It can result from oxidation of CO to CO 2 by ozone (induced by ozone co‐adsorption on Co) or the oxidation of the Co nanoclusters to Co x O y. Oxidation states lower than +4 cannot be detected; the peak at 226.1 eV is due to emission from the S 2s level. Dicobalt octacarbonyl is spontaneously combustible, highly flammable, pyrophoric .
