a Schematic illustration of Pt SAs dispersed on TiO2-nanosheet, in which dark gray surface represents the anatase (001) surface. b Corresponding atomic model for the (001) surface. Blue and red spheres represent Ti and O atoms. HAADF STEM images of TiO2-nanosheet (c, d) and Pt(0.05)/TiO2-nanosheet (e). f Schematic illustration of Pt SAs dispersed on TiO2-truncated bipyramid, in which light gray surface represents anatase (101) surface. g Corresponding atomic model for the (101) surface. HAADF-STEM images of TiO2-truncated bipyramid (h, i) and Pt(0.05)/TiO2-truncated bipyramid (j). The Pt SA is highlighted within the dotted yellow circle in (e) and (j).
