Synthesis of uniform ZnGa2O4 nanoparticles with high photocatalytic activity

- Uniform ZnGa2O4 nanoparticles are obtained by microwave homogeneous coprecipitation.
- CTAB benefits ZnGa2O4 improving separation of photoinduced electrons and holes.
- Microwave and calcining temperatures are optimized for the morphology of ZnGa2O4.
- ZnGa2O4 nanoparticles show superior photocatalysis in degradations of organic dyes.
