Tetragonal faceted-nanorods of anatase TiO2 with a large percentage of active {100} facets and their hierarchical structure

Highly uniformed tetragonal faceted-nanorods (TFNRs) of anatase TiO2 enclosed by active {100} facets with narrow size distribution are obtained with high-yield (>90%). In addition, hierarchically structured anatase TiO2 which consist of TFNRs are also prepared, and the sizes of the TFNR components could be tuned.
