Magnetically separable Fe3O4-Ag3PO4 sub-micrometre composite: facile synthesis, high visible light-driven photocatalytic efficiency, and good recyclability

A magnetically separable Fe3O4-Ag3PO4 sub-micrometre composite was synthesized in large quantities by a fast and simple route, and was demonstrated to have a high photocatalytic efficiency toward the decomposition of methylene blue dye under visible light irradiation with a good recyclability.
