Abstract EN
Hierarchical flower-like Bi2WO6 was successfully synthesized by facile hydrothermal method at low pH.
And Ag/AgCl was loaded by photoreduction on its surface.
As-prepared photocatalysts were characterized by various techniques.
Bi2WO6 was successfully synthesized at a size of 2-3 μm.
Depositing Ag/AgCl did not destroy the crystal structure, and both Ag+ and metallic Ag0 were found.
The band gap of the composite was 2.57 eV, which indicates that visible light could be the activating irradiation.
In the photocatalytic activity test, the composite with 10 wt% Ag/AgCl boasted the highest removal efficiency (almost 100%) in 45 min.
The significant enhancement can be attributed to the surface plasmon resonance (SPR) effect and the establishment of heterostructures between Ag/AgCl and Bi2WO6.
A possible mechanism of photocatalytic oxidation in the presence of Ag/AgCl-Bi2WO6 was proposed.
This work sheds light on the potential applications of plasmonic metals in photocatalysis to enhance their activities.
