Figure 1.

Crystal structure and morphology of the as-prepared pure TiO2nanocrystals. (a) XRD pattern, (b) TEM image, and (c, d) HRTEM images of as-prepared pure TiO2 nanocrystals with a high percentage of {001} facets (note that the insert in (b) demonstrated the schematic geometry of as-prepared pure TiO2 nanocrystals).
