Abstract
The Nickel substituted Cu-Co-Zn-Ce nano ferrites, Zn0.15Co0.45Cu0.40-xNix Fe1.85Ce0.15O4 with x=0, 0.1, 0.20, 0.30, 0.40, were synthesized using the coprecipitation technique. The sample were sintered at 900 ℃ for 5h. The structural, electrical, dielectric and magnetic properties of all the prepared samples were characterized by XRD, SMU2401, UV-Vis and FTIR. The powder X-ray diffraction patterns of all the prepared samples confirmed the formation of single-phase cubic spinel structures. These samples further characterized for the electrical properties by using two-probe type method. The DC resistivity of all the ferrite composition decreased as the temperature increased, showing their semiconductor nature. UV-Vis and FTIR confirmed the substitution of nickel in Cu-Co-Zn-Ce ferrites. From UV-Vis it is observed that the optical band gap changes from 3.9 eV to 5.3 eV with addition of Ni. FTIR analysis revealed that a strong variation on tetrahedral absorption frequency band is present which is due to the replacement of Ni on Cu. All these results suggested that these materials can be used for wastewater treatment.
