synthesis and characterization of cofe2o4 nanoparticles and its application in removal of reactive violet 5 from water

Because of its unique features, including optical, magnetic, and crystalline properties, cofe2o4 magnetic nanoparticles have gotten a lot of interest in photocatalytic process. in this work, cofe2o4 magnetic nanoparticles is applied to effective removal of reactive violet 5 as a water organic pollutant. for this purpose, the cofe2o4 magnetic nanoparticles is fabricated by a hydrothermal method at 170 °c for 12 h. then, the crystalline structure, shape and size of the prepared cofe2o4 nanoparticles are characterized by x-ray powder diffraction (xrd) and scanning electron microscope (sem) methods. the performance of any photocatalyst depends on optical band gap energy of photocatalyst. so, the optical properties of the prepared cofe2o4 nanoparticles are investigated by the uv-vis spectroscopy. the optical band gap of cofe2o4 magnetic nanoparticles (2.41 ev) lead to excellent photocatalytic properties of cofe2o4 nanoparticles. the obtained results showed that the prepared cofe2o4 nanoparticles could effectively degrade reactive violet 5. the 76.4% of reactive violet 5 was degraded in 75 minutes under visible light irradiation.
