Photocatalytic reduction of Cr(VI) with TiO2 film under visible light

- A system photoreduction process on the principle of dye-sensitized solar cells.
- Light absorption and charge separation are performed in the DSC zone.
- Cr(VI) reduction with transferring electrons was conducted at catalysis zone.
- The high efficiency reactor system can handle Cr(VI) and phenol concurrently.
- The system affords a platform to realize the environment improvement.
