Figure 1

HAADF–STEM image of the SPP-treated TiO2 powder (a) on a 5 nm scale; high-resolution lattice image on a 0.2 nm scale indicated in (b) the red box (anatase (101) phase) and (c) the yellow box (anatase (001) phase) in (a); HAADF–STEM images of the SPP-treated ST-1 TiO2 powder measured in the bulk-region (d–f) brookite (100) phase and (g–i) brookite (010) phase. (j) TEM image of the SPP-treated ST-1 TiO2 (the dotted line represents the amorphous shell); and (k) energy-dispersive X-ray spectroscopy results obtained from (a) (Ti and O).
