Tailoring the microstructure of pristine TiO_2 is essential to narrow its band gap and prolong the charge lifetime. In particular, strategies involving fluorine have been used successfully to tune the surface chemistry, electronic structure, and morphology of TiO_2 photocatalysts to improve their photocatalytic activity based on the strong complexation between fluoride ions and TiO_2 and the high electronegativity of fluorine. In this review, we summarize the strategies involving fluorine to establish highly efficient TiO_2 photocatalytic systems or fabricate highly efficient TiO_2 photocatalysts. The main fluorine effects (i.e. the effects of fluorine on photocatalysis) include the following four aspects: (1) Surface effects of fluoride on TiO_2 photocatalysis, (2) effects of fluorine doping on TiO_2 photocatalysis, (3) fluoride-mediated tailoring of the morphology of TiO_2 photocatalysts, and (4) the effects of fluorine on non-TiO_2 photocatalysis. Additionally, the unique applications of these fluorine effects in photocatalysis, including selective degradation of pollutants, selective oxidation of chemicals, water-splitting to produce H2, reduction of CO_2 to produce solar fuels, and improvement of the thermostability of TiO_2 photocatalysts, are reviewed.
