Abstract

Electronic and optical properties of pure, N-doped, Fe-doped and (N, Fe)-codoped anatase TiO2 were evaluated, respectively, by using the density functional theory. The results indicate that the elemental doping narrows the band gap of TiO2 and realize its visible-light response activity; and incorporation of Fe into N-doped TiO2 further increases the photocatalytic activity under visible-light irradiation compared with that of the N-doped TiO2.
