Multiple heterojunction system of Bi2MoO6/WO3/Ag3PO4 was
designed via constructing binary heterojunction Bi2MoO6/WO3, followed by
the deposition of nano-Ag3PO4 on the surface of Bi2MoO6/WO3. Various
techniques were employed to characterize the properties of the asprepared catalytic system. In this study, the decomposition efficiency of
C.I. reactive blue 19 (RB-19) was used as a measure of photocatalytic
activity and the Bi2MoO6/WO3/Ag3PO4 composite exceeded its stand-alone
components (pristine Ag3PO4, WO3/Ag3PO4 and Bi2MoO6/Ag3PO4) by 3.16
times, 2.63 times and 1.75 times, respectively. The photocatalytic tests
implied that the construction of multiple heterojunction could achieve
efficient separation of photo-generated electrons and holes. A possible
photocatalytic mechanism for Bi2MoO6/WO3/Ag3PO4 system was also proposed
according to the results of trapping experiments.
