On the Surface Chemistry of Iron Oxides in Reactive Gas Atmospheres

How details come to surface: The surface chemistry of small and large iron oxide crystallites was investigated in CO and H2 by in situ XPS. Small particles reacted more dynamically to the changing experimental conditions than larger ones. Ab initio atomistic thermodynamics helped shed light on the enigmatic iron/carbon chemistry.
