Fe3O4@BiOCl@GO Core/shell heterojunction nanocomposite as a magnetically recyclable photocatalyst for complete visible light degradation and deep mineralization of dyes in wastewater

Year: 2025

Type: article

Abstract: A novel magnetic Fe₃O₄@BiOCl@GO core/shell heterojunction was synthesized and evaluated for photocatalytic degradation of methyl orange (MO) under visible light. The nanocomposites were characterized by TEM, FE-SEM, UV-Vis DRS, VSM, and XRD. Under optimal conditions, Fe₃O₄@BiOCl@GO achieved 100% degradation within 60 minutes, outperforming the individual components. The enhanced activity is attributed to the synergistic effects of the Fe₃O₄ magnetic core, BiOCl photoactive shell, and GO conductive network, which improved charge separation and reduced the optical band gap. Kinetic analysis followed a pseudo-first-order model, and recyclability tests confirmed high stability and easy magnetic recovery, highlighting its potential for wastewater treatment.
