英文摘要	In this work, we attempted to assemble Ag3PO4 nanoparticles on the surface of rose flower-like Bi2WO6 hierarchical architectures to form Ag3PO4/Bi2WO6 p-n heterojunction. First, rose flower-like Bi2WO6 hierarchical architectures were synthesized via a hydrothermal route. Then, Ag3PO4 nanoparticles were assembled on the surface of Bi2WO6 hierarchical architectures via an ion-exchange method. The as-prepared Ag3PO4/Bi2WO6 composites were systematically characterized by means of XRD, SEM, TEM, XPS, UV-Vis DRS, EIS and photocurrent response. It is demonstrated that the composites exhibit an enhanced separation efficiency of photogenerated electron-hole pairs, which is attributed to the carrier transfer between Ag3PO4 and Bi2WO6. Rhodamine B was chosen as the target organic pollutant to evaluate the photocatalytic activity of Ag3PO4/Bi2WO6 composites under simulated sunlight irradiation. It is revealed that the composites exhibit a significantly enhanced photocatalytic activity compared to bare Bi2WO6. The first-order reaction rate constant suggests that the photo-catalytic activity of 20wt%Ag3PO4/Bi2WO6 composite with 20% Ag3PO4 content is about ten times higher than that of bare Bi2WO6. The involved photocatalytic mechanism was discussed.
