Abstract
Bi2WO6-WO3heterojunctions were first prepared using hydrothermal method with the assistance of cetyltrimethylammonium bromide (CTAB). And Bi2WO6-WO3was further fabricated by depositing Pt on the surface using the photo-assisted deposition method. These catalysts were characterized by XRD, SEM, FTIR, BET and DRS. It is found that Pt-Bi2WO6-WO3acting as a novel visible light-driven photocatalyst exhibited excellent photocatalytic activity in degradation of Methyl Orange (MO) under visible light irradiation. The highest photocatalytic activity of Pt-Bi2WO6-WO3photocatalyst is attributed to the synergistic effect of Pt surface plasmon resonance and Bi2WO6-WO3heterojunction structure.
