Visible Light-Driven Ag3po4@Resin Core-Shell Microspheres For Photocatalytic Degradation Of Methylene Blue

A facile approach for fabricating Ag3PO4@resin core-shell composite microspheres as a visible-light-driven photocatalyst has been successfully established. Results revealed that Ag3PO4@resin core-shell composite microspheres can be synthesized using simple anion-exchange reactions. The prepared composite microspheres exhibited a good potential of degrading 2.5 mg.L-1 methylene blue solution with a high decoloring efficiency of 99.2% under visible light irradiation for 150 min. Microcalorimetric analysis revealed that the microspheres can effectively degrade methylene blue and decrease its toxicities to soil microorganisms. HPLC analysis showed that the microspheres can degrade phenol at a rate of 99% in 4 h under visible light.
