Synthesis and photocatalytic activity of graphene based doped TiO2 nanocomposites

- Graphene based doped TiO2 nanocomposites were prepared.
- The intimate contact between doped TiO2 and graphene is achieved simultaneously.
- These nanocomposites showed higher photocatalytic activity than TiO2 and doped TiO2.
- Photocatalytic mechanism was explained thoroughly.
