Implication

Experimental study demonstrates comparable catalytic carbon monoxide oxidation activities for bridging and on-top oxygen on RuO2(110), indicating complex surface reaction mechanisms.

Key Points

To determine whether weakly bound on-top oxygen on RuO2(110) provides higher catalytic carbon monoxide oxidation activity than bridging oxygen species.
Conducted temperature-programmed reaction experiments to track carbon monoxide oxidation dynamics on RuO2(110) surfaces.
Used isotope labeling to distinguish and quantify the reactivity of bridging versus on-top surface oxygen species.
Revealed that weakly bound on-top oxygen species and bridging oxygen atoms exhibit similar reaction activities in oxidizing carbon monoxide on RuO2(110).
Demonstrated that weaker oxygen-surface bonding does not unilaterally drive enhanced catalytic oxidation rates under oxidizing conditions.
