Facile synthesis of TiO2/trititanate heterostructure with enhanced photoelectric efficiency for an improved photocatalysis

- TiO2/trititanate heterostructure was prepared by a facile hydrothermal method.
- Trititanate can be formed via the direct conversion of surface TiO2.
- The coupled nanostructure possesses enhanced adsorption ability than the bare TiO2.
- Photocurrent of TiO2/trititanate is ca. 2 times as high as that of TiO2.
- TiO2/trititanate nanostructure exhibits good reusability for the removal of RhB.
