Nb2O5/TiO2 heterojunctions: Synthesis strategy and photocatalytic activity

- In situ hydrolysis-loading of Nb2O5 on rutile TiO2 developed as new strategy to heterojunctions.
- Photocatalytic activity greatly promoted via the formation of Nb2O5/TiO2 heterojunctions.
- Nb2O5 acting as oxidation sites and TiO2 acting as reduction sites during photocatalytic reaction.
