Through the citrate-gel auto-combustion technique, we synthesized Co-doped cadmium nano ferrites (NFs) with the formula CoxCd1−xFe2O4 (where 0 ≤ x ≤ 1.0 with increments of 0.2). The synthesized materials underwent comprehensive analysis utilizing X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy. Magnetic and electrical properties were evaluated using a vibrating sample magnetometer and LCR meter, respectively. XRD analysis confirmed the spinel phase structure and FD3M space group. SEM analysis revealed agglomerations of nanoparticles and grain boundaries. Elemental analysis of the synthesized nanomaterials was provided by energy dispersive spectroscopy. FTIR spectroscopy identified two main broad bands corresponding to the tetrahedral (A) and octahedral (B) sites, confirming the spinel structure. Magnetic properties such as magnetic saturation, coercivity, and remanent magnetization were characterized using VSM. Additionally, the LCR meter assessed frequency and temperature-dependent dielectric parameters, including AC conductivity (σAC), dielectric permittivity, dielectric loss (tan δ), and impedance spectra. An increase in AC conductivity (σAC) was observed with increasing temperature and frequency.

“…The acid red is organic azo dye which is widely used as a coloring agent in textile industries. contaminant in dye waste e uents, was used to evaluate the e cacy of photocatalysts (Venkatesh, Kumar, et al, 2023b). Using acid red usual optical absorption maxima at 530 nm, the photocatalytic degradation process was observed.…”

Cobalt based nanoferrites Co 1 − x Cu x Ce y Fe 2−y O 4 Where nano ferrites produced through citrate gel auto combustion technique and their structural and topographical studies were inspected through x-ray diffraction technique and eld emission scanning electron microscope. The structural analysis con rms 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. Catalytic activity of the samples con rmed by dye degradation studies of methylene blue and acid red dye degradation. 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. Electrical properties were measured by LCR meter.
