a) Schematic illustration of the cooparation of Pt and Ni(OH)2 to enhance HER properties. Reproduced with permission.92 Copyright 2011, American Association for the Advancement of Science. b) STM image (200 nm × 200 nm) from the FeO1‐x/Pt(111) surface. Inset is an atomic‐resolution STM image of FeO monolayer nanoislands (25 nm × 20.8 nm) recorded at liquid N2 temperature. c) Dependence of reactivity of CO oxidation on the periphery density (edge density). d) Schematic structure of the Coordinatively unsaturated ferrous (CUF) sites and calculated transition states of O2 dissociation (the inset shows the top view) at the boundary between FeO and Pt(111). The calculated adsorption energies (in eV) for CO and O2 molecules on Pt(111) and FeO1‐x/Pt(111) surfaces are different. Reproduced with permission.94 Copyright 2010, American Association for the Advancement of Science. e) There can be found five types of FeO1‐x/Pt edge structures. Here is a brief summary of them.
