Photocatalysis of cobalt zinc ferrite nanorods under solar light

摘要

Co0.7Zn0.3Fe2O4 nanorods were synthesized from hydrazine precursor by co-precipitation technique. Infrared and thermogravimetric-differential thermogravimetric curves of the precursor indicated the bridging bidentate nature of hydrazine and three-step thermal decomposition. The as-synthesized cobalt zinc ferrite nanorods were characterized by powder X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, transmission electron microscopy, vibrating sample magnetometry and UV-diffuse reflection spectroscopy which proposed the phase structure, morphology, magnetic and optical properties. Co0.7Zn0.3Fe2O4 nanorods showed a sensible photocatalytic activity on Congo red, Malachite green, Methylene blue, Methyl red, Rhodamine B and Rose bengal under solar light at different time intervals and were magnetically separated.
