Photocatalytic Degradation of Methyl Orange over Nitrogen–Fluorine Codoped TiO2

Anatase type nitrogen-fluorine (N-F) codoped TiO2 nanobelts were prepared by a solvothermal method in which amorphous titania microspheres were used as the precursors. The as-prepared TiO2 nanobelts are composed of thin narrow nanobelts and it is noted that there are large amount of wormhole-like me
