| Abstract: | The fabrication of well defined hierarchical structures of anatase TiO2 with a high percentage of reactive facets is of great importance and challenging.Hierarchically flower-like TiO2 superstructures (HFTS) self-assembled from anatase TiO2 nanosheets with exposed {001} facets (up to 87%) were synthesized by a simple alcohothermal strategy in a HF-H2O-C2H5OH mixed solution using titanate nanotubes as precursor.The samples were characterized by X-ray diffraction,scanning electron microscopy,transmission elec... |
