Iron-carbon-codoped mesoporous titania nanocrystallines were synthesized by a modified sol-gel method based on the self-assembly technique using polyethylene glycol sorbitan monostearate (Tween 60) as template. The samples were characterized by X-ray diffraction, N_{2} adsorption, UV-vis diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy, photoluminescence, electrochemical impedance spectroscopy, and transient photocurrent responses analysis. The photocatalytic activity of Fe-C-codoped TiO_{2} nanoparticles were evaluated by the degradation of methyl orange (MO), p-nitrophenol (PNP) and biphenol A (BPA) under visible light irradiation. It was found that the as-prepared Fe-C-codoped TiO_{2} sample showed excellent photocatalytic activity compared to undoped TiO_{2}. The highest activity was obtained for Fe-C-codoped TiO_{2} sample calcined at 520°. The enhanced photocatalytic performances were attributed to the synergetic effects of good crystallizing action, appropriate phase composition and slow recombination rate of photogenerated charge carriers. Based on the experimental results, a reasonable photocatalytic mechanism of as-prepared Fe-C-codoped TiO_{2} photocatalysts was also proposed and discussed.
