Effective role of trifluoroacetic acid (TFA) to enhance the photocatalytic activity of F-doped TiO2 prepared by modified sol-gel method

- Surface-fluorinated TiO2 with superior properties.
- Generation of free surface hydroxyl radicals.
- Excellent photo-generated electron and holes separation.
- Mixed morphologies of truncated and compressed bipyramids.
- Superior photo-kinetics performance.
