A nonaqueous sol-gel route to highly water dispersible TiO2 nanocrystals with superior photocatalytic performance

- Highly water dispersible TiO2 nanocrystals were synthesized via a facile nonaqueous sol-gel method.
- TiO2 nanocrystals were 5-10 nm in diameter and modified with carbonaceous species.
- Carbonaceous species endow TiO2 nanocrystals with highly water dispersible property and superior photocatalytic activity.
