Photocatalysis of cobalt zinc ferrite nanorods under solar light
- 56 Downloads
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.
