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.
