Abstract

This study presents the green synthesis of CuFe₂O₄ and Clay/CuFe₂O₄ composites using neem leaf extract via a reflux method. The materials were comprehensively characterized through XRD, SEM, FTIR, EDX analysis, and UV–Vis spectroscopy. The photocatalytic efficiency was assessed for the degradation of Methyl Violet (MV) dye under UV light, achieving an outstanding 94.04 % degradation efficiency with the Clay/CuFe₂O₄ composite at an initial dye concentration of 10 ppm within 60 min. The reaction adhered to first-order kinetics, with a calculated half-life of 15.33 min. Furthermore, antioxidant activity evaluated using the DPPH assay exhibited a notable scavenging efficiency of 87.05 % and an IC₅₀ value of 223.03 μg/mL for the Clay/CuFe₂O₄ composite, surpassing the performance of its individual components. These findings underscore the potential of Clay/CuFe₂O₄ composites for environmental remediation and antioxidant applications.
