Titanate nanowires with layered structure were synthesized through hydrothermal reaction between TiO2 powder and NaOH aqueous solution at the temperature 175℃-240℃. Influence of experimental parameters, such as molar ratio of reagents NaOH/TiO2 and reaction temperature were studied. The structure of the nanowires was studied using X-ray diffraction, electron microscopy and energy-dispersive X-ray spectroscopy. There were a lot domain boundaries and defects observed in the nanowires. The structure of the nanowires was found not to be the same with any known structure. The structure can be indexed using a monoclinic unit cell with a=2.15nm, b=0.377nm, c=1.28nm, β=103.5°. Moreover, K2Ti8O17 nanowires were fabricated through hydrothermal reaction between the synthesized sodium titanate and KOH aqueous solution.
