Serious health issues, including cancer, redness, skin irritation, and allergic reactions, have been linked to factories releasing Congo red dye into water supplies. Therefore, this study focused on the simple production of NiO/CoO (NCO) metal oxide nanocomposites using the reflux-assisted chemical precipitation method. Subsequently, these metal oxide nanocomposites were employed for effective photocatalytic degradation of Congo red dye. The crystalline structure and phase purity of the synthesized materials were analyzed using X-ray diffraction, confirming the formation of highly crystalline cubic phases of NiO, CoO, and NCO nanocomposite. Morphological studies showed that the NCO composite exhibited a mixed spherical and square-shaped morphology, indicating efficient interfacial interaction between NiO and CoO. The synergistic combination of NiO and CoO in the composite enhances the material's structural and surface characteristics, making it a promising photocatalyst for Congo Red (CR) dye degradation. This work presents a simple, cost-effective synthesis approach for developing efficient metal oxide nanocomposites for environmental cleanup.
