TiO2 nanotubes were synthesized from commercial rutile powder by means of the hydrothermal method in alkaline solution at temperature of 150℃ for 48hours. The morphology and structure evolutions were characterized with SEM，TEM and X-ray diffraction. The TiO2 nanotubes mixed with Triton X-100 and acetyl acetone were screen-printed onto the glass substrate coated with a transparent conducting oxide (ITO，or tin-doped indium oxide)，then sintered at 450℃ for 30 minutes to form porous photoanode of dye-sensitized solar cells. A solar cell withactive area of 0.28cm2 was assembled with N719-coated nanotube-TiO2 electrode，Pt-coated ITO glass and iodide-based ionic liquid electrolyte. The J-V curve was measured using a standard solar simulator (AM1.5 spectrum，100mW/cm2)，and a photoelectric conversion efficiency of 2.17% was obtained.
