Abstract
The magnetically doped TiO2 nanotube arrays were prepared in 0.25% (mass fraction) NH4F/glycerol including a certain amount of Fe3O4 nanoparticles using the method of anodic oxidation of a pure titanium sheet at a constant potential. The obtained nanotubes film were characterized by Field Emission Scanning Electron Microscope (FESEM), X-ray Diffraction (XRD), Transmission Electron Microscope (TEM) and Photoelectric Performance Test. Neat and orderly TiO2 nanotube arrays with Fe3O4 distuibuted evenly have been synthesized using the electrolyte doping method (add 0.1mol/L of the prepared Fe3O4 in the electrolyte). Photoelectric conversion efficiency of Fe3O4 doped TiO2 nanotubes is higer than that of pure TiO2 nanotubes.
