Hydrothermal Synthesis and Photocatalytic Properties of BiPO₄/Ag₃PO₄ Heterostructure for Phenol Decomposition

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.
