Template-free synthesis of Fe3O4 nanorod bundles and their highly efficient peroxidase mimetic activity for the degradation of organic dye pollutants with H2O2

Abstract

Highly crystalline Fe₃O₄ nanorod bundles were synthesized via a facile template-free method. The high surface to volume ratio of Fe₃O₄ nanorods facilitates the excellent activation of H₂O₂via their peroxidase mimetic activity for the degradation of crystal violet (CV) as a model organic dye pollutant. The self sensitization of CV dye by solar irradiation also indirectly helps in the photo-Fenton-like degradation process.
