The formation of Zinc Nickel Ferrites Systems Nanocomposites (ZNFONCs) through Ethylene glycol (PEG) surfactant was achieved by chemical co-precipitation technique. Their structure, shape, and constituents were investigated by X-ray diffraction, dispersion, and scanning electron microscopy. The photocatalyst effect of Zinc-Nickel ferrite system Nanocomposites was determined by methyl Blue (MB), when exposed to ultraviolet light. Magnetization estimation by vibrating magnetometer at room temperature is an additional effort in the present work. © 2020, AMG Transcend Association. All rights reserved.
