F-doped TiO2 nanorods are prepared at 100 °C and atmospheric pressure in the presence of NaF, which show superior photocatalytic activity for the degradation of methylene blue under UV and visible irradiation.
The aspect ratio of rutile TiO2 nanorods is a key factor influencing photocatalytic MB degradation. The conduction band potential plays significant roles in the photocatalytic reduction of Cr(vi).
