The cobalt (Co{sup 2+}) has been successively substituted in ZnCuFe{sub 2}O{sub 4} to obtain Zn{sub 0.5−x}Co{sub x}Cu{sub 0.5}Fe{sub 2}O{sub 4} (0.0 ≤ x ≤ 0.5) ferrites by auto-combustion technique. Prior to photocatalytic degradation, all as-synthesized ferrites were characterized to study their structure, composition, morphology, magnetic and optical behavior. The shifting of tetrahedral as well as octahedral stretching peaks towards higher frequencies observed in the Fourier transform infrared spectroscopy indicates that Co{sup 2+} ion is substituted in ZnCuFe{sub 2}O{sub 4}. X-ray diffraction pattern confirms the formation of single-phase cubic spinel with decrease in average lattice constant from 8.3915 to 8.3224 Å with increase in Co{sup 2+} substitution. The photocatalytic performance of obtained ferrite catalyst was determined using methylene blue (MB) as model dye under visible light and direct sunlight. The degradation of MB with as-obtained photocatalyst under sunlight improves (91%) which proves the effective utilization of visible light active magnetic photocatalyst.
