In situ fabrication of novel Z-scheme Bi2WO6 quantum dots/g-C3N4 ultrathin nanosheets heterostructures with improved photocatalytic activity

- We designed and fabricated novel Bi2WO6 QDs/g-C3N4 heterojunction structures.
- Novel Bi2WO6 QDs/g-C3N4 catalysts were constructed by one-pot hydrothermal route.
- The catalysts show highly efficient solar light catalytic activity.
- Z-scheme mechanism was proposed to explain the enhanced catalytic activity.
