Graphene-spindle shaped TiO2 mesocrystal composites: Facile synthesis and enhanced visible light photocatalytic performance

- Graphene-TiO2 mesocrystal composites were fabricated via a facile approach.
- Graphene sheets were decorated with spindle-like TiO2 mesocrystals.
- Graphene causes enhanced light absorbance and visible light photocatalytic activity.
- Oxygen-containing radicals are believed to responsible for its improved activity.
