(a,o) TEM images, (b–e,p–s) top-view elemental mapping images, and side-view atomic-resolution HAADF-STEM images (f,t) and EELS elemental maps (g–j,u–x) of BOC-MS/Pt and BOC-MS/MnOx. Scale bar, 500 nm, 10 Å, 600 nm and 10 Å, in a,f,o,t, respectively. (k) AFM image and (l) KPFM image of BOC-MS. Scale bar, 500 nm in k. (m) Height profiles along the lines in image (k,l). Schematic illustration of Pt (n) and MnOx (y) photo-depositions on BOC-MS.
