- •
We firstly report a facile way to prepare the visible-light-driven Ag2O/NaTaO3p–n heterojunction by chemical precipitation method.
- •
The Ag2O/NaTaO3 heterojunction shows the highest photocatalytic activity than the pure NaTaO3 and Ag2O nanoparticles under visible light.
- •
The enhancement of the heterojunction photocatalytic activity was discussed and the photocatalytic mechanism was tested in our paper.
- •
In summary, we think that the Ag2O/NaTaO3 heterojunction with the strong visible light absorption and efficient photocatalytic activity have been extended application in photocatalysis for organic dyes pollutants degradation and purification of water.
