Abstract: Nickel doped copper ferrite nanoparticles Ni x Cu 1-x Fe 2 O 4 (x = 0.1, 0.3, 0.5, 0.7, and 0.9) have been prepared through well known sol-gel technique. Numerous analytical methods, including the Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), and powder X-ray diffractometer (XRD), were used to analyze the synthesized materials. Synthesized sample XRD patterns reveal the single phase development of the spinel crystalline structure in the absence of any contaminant. The concentration of Ni ions rises with a corresponding decrease in crystallite size. Scanning electron microscopy (SEM) was also used to assess the microstructure. By using UV–Visible spectrometer an optical absorbance and through FTIR, two of ferrite's distinctive bands were verified. The M-H loops show that when the concentration of nickel ions increases, saturation magnetization varies. The Cyclic-Voltameter was used to perform the ionic electrochemical analysis. The NixCu 1-x Fe 2 O 4 nanopowder's enhanced magnetic characteristics suggest that these substances would make good candidates for magnetic catalysts. The FTIR spectra inferred that extending vibration of M–O vibrations on both sites of A and B. Enhancing magnetic property through larger saturation magnetization value (11.04 emu/g) with ionization constant (1.867). larger current in 0.5 and larger area in 0.9. • The crystallite size varies with the increase in Ni ion concentration. • The expansion of nickel confining the grain development of spinel ferrite. • Ni x Cu 1-x Fe 2 O 4 suitable for magnetic catalyst. • Non-uniform and agglomeration of nanoparticles. • Larger magnetization with moderate electrochemical behavior.
