Cobalt based nanoferrites Co1−xCuxCeyFe2−yO4 where x = 0.0 to 0.5 with 0.1 nano-ferrites synthesized through citrate gel auto combustion technique and their structural and topographical studies were inspected through X-ray diffraction technique and field emission scanning electron microscope. The structural analysis confirms the prepared nano-ferrites having single-phase cubic spinel, along Fd3m space group. Crystalline size of the synthesized samples found 20–26 nm calculated by Debey Scherrer formula. The FTIR spectrum reveals prominent absorption bands ʋ1 and ʋ2 within the wavenumber range below 1000 cm−1, denoting tetrahedral and octahedral voids. The Raman spectrum of AB2O4 exhibits lattice vibrations expressible through 5Tu1 + A1g + Eg + 3T2g representations for the Fd3m space group, predicted via group theory. Electrical properties were measured by LCR meter. The AC conductivity of the materials increased as increasing frequency. Magnetic behavior of the materials measured by a vibrating sample magnetometer, saturation magnetization gradually decreases as increasing Cu and Ce content and found to be 26 to 18 emu/gm. Catalytic activity of the samples confirmed by dye degradation studies of methylene blue and acid red dye degradation. The sample Co0.9Cu0.1Ce0.1Fe1.9O4 exhibits the highest catalytic degradation activity for methylene blue and acid red. [ABSTRACT FROM AUTHOR] |
