An effective visible-light-driven Ag₃PO₄@CuFe₂O₄ Z-scheme magnetic micro-nanocomposite was successfully fabricated by a simple ion-exchange deposition method. The Ag₃PO₄@CuFe₂O₄ photocatalyst exhibited remarkably enhanced photocatalytic activity (degradation efficiency was ～99% within 30 min and kinetic constant reached 0.1423 min^-1) as compared to Ag₃PO₄ and CuFe₂O₄ for the degradation of Rhodamine B (RhB). Comparing the activity results dependence with the characterization results, which indicated that the dependence of the photocatalytic activity on the efficient separation of photo-generated h⁺-e^- pairs. This study might provide a promising visible light responsive photocatalyst for the photocatalytic degradation of organic dyes in waste water.
