Three-dimensional and dendritic rutile TiO2 nanorods were successfully fabricated on a Ti foil surface using a one-step acidic hydrothermal method. The TiO2 nanorods were characterized using X-ray diffraction (XRD), energy dispersive X-ray spectrometry (EDX), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and optical contact angle testing. The results showed that the nanorods with diameters of 100–500 nm and lengths of 100 nm to 1 μm were obtained on the Ti foil surface. The length and density of the TiO2 nanorods were perfect at the conditions of HCl concentration 0.5 mol/L, temperature 220 °C, and reaction time 12 h. The TiO2 nanorods formed parallel to the consumption of Ti and grew along the (110) direction having a tetragonal rutile crystal. The morphology of the nanorods possessed a three-dimensional structure. The contact angle of the nanorods was only 13 ± 3.1°. Meanwhile, the photocatalytic activities of the TiO2 nanorods were carried out using ultraviolet fluorescence spectrophotometry for the methyl orange detection, and the degradation was found to be about 71.00% ± 2.43%. Thus, TiO2 nanorods can be developed by a one-step acidic hydrothermal method using Ti foil simultaneously as the substrate with a TiO2 source; the TiO2 nanorods exhibited photocatalytic performance while being environment-friendly.

Here we synthesized a high-density single crystal anatase phase TiO2/ITO nanorods array composite by one-step hydrothermal method. TiCl4, H2O, and HCl were used as the titanium precu-rsor, oxygen source, and inhibitors, respectively. The TiO2 nanorods array were analyzed using X-ray diffraction (XRD), energy dispersive X-ray spectrometer (EDX), scanning electron microscopy (SEM), optical contact angle tester and ultraviolet-fluorescence spectrophotometer, separately. The nanorods in the composite grew along the [101] crystal plane, with a diameter of about 500 nm and a length of about 3 μm. The effect of PVP addition on the crystal phase and morphology of TiO2 na-norod arrays was investigated. When the amount of PVP added was 0.5g, the diameter of nanorods was about 77-120nm, and a neat array structure appeared. In the photocatalytic experiment, methyl orange and acid red were used as degraded materials, the photocatalytic degradation rate was up to about 100%. When the hydrophilicity was the best, the optical contact angle of the sample after ultr-aviolet light irradiation was 7.2°. These results indicated that TiO2 after doping experiments got better photocatalytic properties.
