Abstract:Using Fe-doped titania powders as the precursor, Fe-doped TiO2 nanotubes with small diameter of 10nm were obtained by hydrothermal method. The doped titania powders have two different crystalline phases, anatase and rutile of which the average particle diameters are 30.3nm and 41.7nm, receptively. The products were characterized by TEM, XRDand EDS. The results showed that Fe-doped TiO2 nanotubes of 200nm in length could be obtained from Fe-doped rutile powder, and have higher yields. The formation mechanism of long titania nanotubes was suggested in the light of the relative stability of crystalline phase.
Keywords:hydrothermal method  titania  doping  nanotube
