Abstract

The heterostructures of BiPO4/Ag3PO4 were synthesized using a hydrothermal method with starting materials of Bi5O(OH)9(NO3)4, AgNO3 and Na2HPO4.12H2O at pH 1 under heating of 180°C for 12 h. The products were characterized using XRD, DRS and BET specific surface area. The photocatalytic activities were determined through the phenol decomposition under UV light (λ=390 nm) and blue light (λ=445 nm) irradiation. The heterostructures of BiPO4/Ag3PO4 with the body-centered cubic structure of Ag3PO4 and monoclinic of BiPO4 were successfully synthesized. The photocatalytic activity of BiPO4 under UV light irradiation could be enhanced by designing of BiPO4/Ag3PO4 heterostructure with the molar ratio of 0.75/0.25.
