| description | For the successful production of NiO/NiCo<sub>2</sub>O<sub>4</sub> nanocomposites, the environmentally friendly method of egg white supplementation has been used. Several analytical techniques were employed to characterize the morphology, purity, and crystal structure of the as-prepared nanocomposites. These techniques included transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The physical adsorption and magnetic properties of the investigated composite were determined using the Brunauer–Emmett–Teller (BET) method and a vibrating-sample magnetometer (VSM), respectively. The results have shown that the as-prepared composite particles had diameters of about 10–25 nm, with uniform distribution. The XRD analysis showed that the as-synthesized composites consisted entirely of cubic structures of both NiO and spinel NiCo<sub>2</sub>O<sub>4</sub> nanoparticles, with a space group of Fd3m. The FTIR analysis showed characteristic vibration modes related to metal oxides, confirming the formation of composites containing NiO and NiCo<sub>2</sub>O<sub>4</sub> crystallites. The investigated composites’ saturation magnetization (M<sub>S</sub>) and coercivity (H<sub>C</sub>) were easily controllable because of the ingredients’ ferromagnetic (NiCo<sub>2</sub>O<sub>4</sub>) and antiferromagnetic (NiO) characteristics. The excellent combination of the NiO/NiCo<sub>2</sub>O<sub>4</sub> nanocomposites’ properties is anticipated to make this system suitable for a wide range of applications. |
