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.

CuFe2O4和Clay/CuFe2O4纳米复合材料的绿色合成和回流法及其光催化和抗氧化研究

以印楝叶提取物为原料，采用回流法绿色合成CuFe2O4和Clay/CuFe2O4复合材料。通过XRD、SEM、FTIR、EDX、UV-Vis等方法对材料进行了全面表征。在紫外光下对甲基紫（MV）染料的光催化降解效率进行了评估，在初始染料浓度为10 ppm时，在60 min内，粘土/CuFe2O4复合材料的降解效率达到了94.04%。该反应符合一级动力学，计算半衰期为15.33 min。此外，DPPH法测定的抗氧化活性表明，Clay/CuFe2O4复合物的清除率为87.05%，IC50值为223.03 μg/mL，超过了其单个组分的性能。这些发现强调了粘土/CuFe2O4复合材料在环境修复和抗氧化应用方面的潜力。
