N-doped BiPO4 photocatalysts were successfully synthesized via a facile microwave hydrothermal method. XRD, Raman, and XPS results confirmed that the nitrogen atoms were incorporated into the lattice of BiPO4 to replace oxygen atoms. The doped nitrogen did not affect the crystalline structure of BiPO4. With the increase of nitrogen content, the nanorod sizes of N-doped BiPO4 were decreased gradually compared with those of pure BiPO4. The photocatalytic activity of N-doped BiPO4 was remarkably improved. Greater than 96% photodegradation of RhB under the exposure of UV light was achieved within 15 min with 21 at%, and its degradation rate was about 2.1 times greater than pure BiPO4. This phenomenon could be attributed to the fact that the nitrogen doped into BiPO4 improved the separation efficiency of photogenerated electrons and holes.
