Anatase TiO_2 single crystals with exposed(001) facets were successfully synthesized by a one-step hydrothermal route using Ti F_4 as raw material. The crystal phase, morphology, microstructure, and photoabsorption of the samples were analyzed by field emission scanning electron microscope(FE-SEM), transmission electron microscope(TEM), X-ray diffraction(XRD), and ultraviolet-visible diffuse reflectance spectra(UV-Vis DRS). The influences of hydrothermal temperature and p H of solution on morphology of TiO_...
