Lattice doping: Substitutionally and interstitially V-doped TiO2 are investigated by first-principles DFT calculations in the framework of the GGA+U approach (see figure). By analyzing the geometrical structure, the formation energies, and the electronic structure it is found that substitutionally doped anatase [V4+ (3d14s0)] is responsible for the experimentally reported visible-light photocatalytic activity.
