Figure 1: STM images of benzaldehyde formation at the FeO/Pt(111) interface.
From: Metal/oxide interfacial effects on the selective oxidation of primary alcohols
(a) FeO islands on Pt(111) expose O-terminated steps after the annealing in 1.0 × 10−7 mbar O2 at 400 K. (b) FeO nanoislands with O-terminated steps after the exposure of ∼1 L benzyl alcohol at 300 K, followed by flash annealing to 350 K. (c) FeO nanoisland with Fe-terminated edge after the exposure of ∼1 L benzyl alcohol at 300 K. (d) The magnification of an FeO island in b with adsorbed species at the FeO/Pt(111) interface. (e) Line profiles of adsorbed species: blue line for the species marked in c and the red line for the species in d. Image sizes and scanning conditions: (a) 43 nm × 43 nm, Vs=0.4 V, It=0.1 nA; (b) 43 nm × 43 nm, Vs=0.6 V, It=0.1 nA; (c) 8.5 nm × 8.5 nm, Vs=0.1 V, It=2.1 nA; (d) 7 nm × 7 nm, Vs=0.1 V, It=0.7 nA.
