Designing high-efficiency heterogeneous photo-assisted Fenton catalysts is the key to harnessing solar energy for promoting the Fenton process in water treatment. Herein we developed nitrogen-doped Fe3C@C particles by thermally treating Fe3O4 precursor with dicyandiamide. The as-prepared Fe-N-C hybrid material was comprehensively characterized by electron microscopy, various spectroscopic techniques and so forth to confirm the compositions and structures. The band gap of nitrogen-doped Fe3C@C particles was about 1.6 eV. Methylene blue was used as a model organic contaminant to test the photo-assisted Fenton activity of the nitrogen-doped Fe3C@C particles, with optimal dosages of H2O2 and the catalyst itself, which showed excellent efficiency in removing the model contaminant, demonstrating that the as-prepared hybrids can work as a highly efficient photo-assisted Fenton catalyst.
