One-pot synthesis of ZnO/ZnGa2O4 heterojunction with X/XY structure for improved photocatalytic activity

- New heterojunction ZnO/ZnGa2O4 with X/XY structure is found.
- A simple one-pot coprecipitation synthesis method is developed.
- Heterojunction has much higher photocatalytic activity.
- The synthetic method has potential commercial value.
