(1 × 1 μm) AFM images of the as-prepared Pt NPs supported on (a) SiO₂/Si(111) and (b) TiO₂(110). (c–e) STM images of polymer-free Pt NPs on TiO₂(110) acquired at 25 °C after annealing in vacuum at 1100 °C. The inset in (c) and the high-resolution images in (d,e) display truncated octahedron Pt NPs on TiO₂(110) with (100) top and interfacial facets. (f) Line profiles of the Pt NPs, shown in (d,e).
