title: Pivotal role of fluorine in tuning band structure and visible-light photocatalytic activity of nitrogen-doped TiO2.
abstract: Synergistic interactions between N and F can be used to tune the band structures of N-doped TiO(2) (see scheme). Reduction potential of conduction band electron is positively shifted to weaken unwanted O(2) reduction, but enhances the target reduction reaction in air. The tuning also enhances the oxidation ability of the valence band to oxidize water to O(2), which makes photocatalytic reduction proceed without any organic sacrificial reagents.
