Figure 2

SEM and TEM images showing the chain structure and the lattice structure of the NPs, and particle size distribution of (a) TiOx-A, (b) TiOx-B, and (c) TiOx-C. Red boxes in the TEM images indicate discontinuous lattices. Some lattice spaces can be associated with reduced titanium oxides, such as Ti3O5 [002] (4.73 Å), Ti2O3 [202] (2.11 Å), Ti4O7 [004] (2.48 Å).
