Caught on film: NO exposed to monolayer FeO(111) film grown on Pt(111) at elevated pressures readily forms a trilayer OFeO film that is virtually identical to that formed with O2. However, CO2 production in the CO+NO reaction is negligible as compared to CO+O2, which is rationalized in terms of the replenishment of oxygen vacancies as the rate-limiting step that proceeds much faster with O2 than NO.
