| description | In this paper, the Fe<sup>3+</sup> doped rutile phase TiO<sub>2</sub> nanotubes arrays (NTAs) were prepared in a low temperature water-assistant crystallization method. It is noteworthy that the Fe<sup>3+</sup> doping hardly hinders either the crystallization of rutile TiO<sub>2</sub> NTAs or the highly-ordered nanotubular morphologies. Moreover, Fe<sup>3+</sup> did not form other compound impurities, which indicated that Fe<sup>3+</sup> substitute Ti<sup>4+</sup> into the lattice of TiO<sub>2</sub>. With the introduction of Fe<sup>3+</sup>, the light absorption range of TiO<sub>2</sub> NTAs extends from the ultraviolet band to the visible light range. Photocatalytic testing results indicate that Fe<sup>3+</sup> doped TiO<sub>2</sub> NTAs can effectively improve the degradation rate of methyl orange aqueous solution in visible light, and the TiO<sub>2</sub> NTAs with 0.2 mol/L Fe<sup>3+</sup> doping exhibits the highest photocatalytic degradation efficiency. |
