Abstract
TiO2 nanotube was synthesized successfully within a range of temperature by hydrothermal process, using P25 powder and NaOH (A. R grade) as the precursor. The titania nanotube was characterized by XRD, TEM, BET, TG-DSC and Uv-vis. These results suggest that the surface area and the length of the nanotube increase and the diameter of the nanotube almost keep a fixed value with the temperatures the productivity of the nanotube also increases with the temperature. The as-prepared nanotube at 150°C with outer diameters of-8 nm has surface area of 641.855 m2/g. The powder prepared at 160°C and then treated at 560°C shows an great enhancement in the photodegradation efficiency of methylene blue under ultraviolet irradiation compared to commercially available P25. As there are few reports in literatures about the influence of synthesis temperature on the titania nanotube, so we study the influence of synthesis temperature on the titania nanotube systematically.
