摘要：

Nanosheet-shaped TiO2 material with a large surface area was synthesized by the reaction of anatase TiO2 with 10 M NaOH aqueous solution at 100 degrees C for 12-48 h and followed by washing with dilute HCl. Numerous nanosheets were aggregated together and formed a dahlia flower. TEM images show that these nanosheets have a rolled edge, suggesting that this material might be an intermediate product in the formation of tubular structural materials. The results of XRD measurement and Laser Raman analysis indicate that the structure of nanosheets is a layered compound, H2Ti3O7.
