Controlled fabrication and enhanced photocatalystic performance of BiVO4@CeO2 hollow microspheres for the visible-light-driven degradation of rhodamine B

- m-BiVO4@CeO2 hollow microspheres were firstly fabricated.
- m-BiVO4@CeO2 was used for photocatalytic degradation of rhodamine B.
- The photocatalytic activity of heterogeneous hollow microspheres is enhanced.
- Photocatalytic mechanism on m-BiVO4@CeO2 by visible light irradiation was proposed.
- Efficient separation of photoexcited charges results in enhanced catalytic activity.
