Evaluating the sensitizing effect on the photocatalytic decoloration of dyes using anatase-TiO2

- The dye adsorption content on A-TiO2 mainly determines the photocatalytic decoloration rate.
- MB, OG, MY and AB24 cannot work as the photo-sensitizer on A-TiO2 because of the unmatched band position.
- The dye-sensitizing effect on the photocatalytic decoloration of RhB is minor.
- The electron/hole pairs from A-TiO2 mainly provide the photocatalytic activity for dye decoloration.
