Magnetic ordered mesoporous copper ferrite as a heterogeneous Fenton catalyst for the degradation of imidacloprid

- Highly ordered mesoporous CuFe2O4 was firstly used as heterogeneous Fenton catalyst.
- Meso-CuFe2O4 showed much higher catalytic activity than meso-CoFe2O4 and Fe3O4.
- Possible heterogeneous catalytic mechanism in meso-CuFe2O4/H2O2 system was proposed.
- Magnetic meso-CuFe2O4 was stable, reusable and easy to separate using a magnet.
