Tunable surface: The surface structure of the Fe–Pt bimetallic catalyst can be reversibly modulated between the iron‐oxide‐rich Pt surface and the Pt‐skin structure with subsurface Fe via alternating reduction and oxidation treatments (see figure). The regenerated active Pt‐skin structure is active in reactions involving CO and/or O.
