Abstract

Slim titanate naotubes was prepared from industrial coarse TiO2 powder by simple sonochemical-hydrothermal processing. The influences of ultrasonic irradiation on TiO2 precursors were investigated. The morphology and crystal structure of the products were characterized by TEM and X-ray diffraction, respectively. The typical products are long nanotubes around 8-10nm in out diameter. Both anatase and rutile TiO2 precursors can be transferred into titanate nanotubes in this sonochemical & hydrothermal processing.
