Abstract
In this study, spinel ferrite nanoparticles—CoFe₂O₄, NiFe₂O₄, CuFe₂O₄ and ZnFe₂O₄ — were synthesized via the solution combustion method and evaluated for the photocatalytic degradation of Allura Red, a persistent azo dye commonly found in industrial wastewater. The rapid combustion process yielded porous, nanostructured ferrites with high surface area, as confirmed by SEM analysis. Structural and elemental integrity was verified using XRD and EDS techniques. Among the synthesized catalysts, variations in morphology and surface characteristics significantly influenced their degradation efficiency of Allura Red dye under visible light irradiation. The CuFe2O4 has been the 91.3% which is least and the ZnFe2O4 shows the highest 97.5% degradation. The results highlight the potential of transition metal ferrites as cost-effective and efficient photocatalysts for environmental remediation. Further synthesized ferrites were showing best results in sensing dopamine, hence this results shows multiple application of the ferrites
