Original Paper: sol–gel and hybrid materials for catalytic, photoelectrochemical and sensor applications


Fibrous cobalt ferrite catalyst was synthesized using the sol–gel method combined with celloulose template. This technology can exactly reproduce the microstructure of cellulose template on nanometer level. The obtained cobalt ferrite was characterized by field emission scanning electron microscope (FESEM), x-ray diffractometry (XRD), fourier transform infrared spectroscopy (FT-IR) and vibrating sample magnetometer. Cobalt ferrite exhibited high efficiency to activate peroxymonosulfate (PMS) for the degradation of Acid Orange 7. The effects of experimental parameters including initial pH values of dye solution, effect of concentrations of PMS and CoFe2O4 on Acid Orange 7 degradation were studied. Furthermore, CoFe2O4 also displayed an extremely high catalytic performance in the degradation of Methyl Orange, Reactive Brilliant Red X-3B, Methylene Blue and Rhodamine B. CoFe2O4 retained high degradation efficiency and high stability even after being reused for five runs. The inherent magnetism of ferrite leads to easy separation of catalyst from the reaction mixtures. Consequently, the catalyst durability is improved remarkably.

CoFe2O4 magnetic fiber nanomaterial was synthesized using the sol–gel method combined with celloulose template and exhibited high catalytic activity for AO7 degradation in presence of peroxymonosulfate.


  • CoFe2O4 was prepared by a facile sol–gel combined with celloulose template technique.

  • CoFe2O4 exhibited high catalytic activity for dye degradation in presence of peroxymonosulfate.

  • CoFe2O4 showed high stability, good reusability and excellent magnetic properties.

  • Sulfate radical was verified to be the main reactive species for AO7 degradation.
