Abstract

F tactic: Highly fluorine-doped mesoporous metal oxides (up to 40 atom %) were synthesized by topotactic fluorination synthesis with mesoporous metal oxides as starting materials and fluorine as the fluorination agent. The surface areas, pore sizes, pore volumes, and F atomic concentrations of these materials could be adjusted over a wide range by varying the fluorination time and temperature.
