A new magnetic Fe₃O₄@C@Ag₃PO₄ nanocomposites photocatalyst with visible light response has been prepared by solvothermal, hydrothermal and precipitation process. The photocatalyst exhibited high photocatalytic activity and stability for the degradation of rhodamine B (RhB). Almost 100% of RhB was photodegraded with the assistance of magnetic Fe₃O₄@C@Ag₃PO₄ nanocomposites after 40 min, and the photocatalyst showed no obvious loss of photocatalytic activity after four times of cyclic utilization. Furthermore, the magnetic Fe₃O₄@C@Ag₃PO₄ nanocomposites can be separated by external magnetic field. Further study proved that the photogenerated holes were the main active species in the degradation process.
