More oxygen! Continuous NO2 dosing on Ag(1 1 1) leads to the sluggish accumulation of an oxygen species, characterized by an O 1s peak at ≈530 eV indicative of the catalytically active oxygen species in the ethylene epoxidation reaction. X-ray photoemission electron microscopy at 530.3 eV evidences the preferential accumulation of this species at step sites (part a). If formation and decay of the Oad-driven Ag surface reconstruction (red O 1s component) is induced by cycled NO2 dosing, the 530 eV oxygen species (blue and green components) accumulates much more efficiently on the surface (part b).
