Synthesis and Characterization of Z-Scheme Plasmonic Ag/AgBr/Bi2WO6 Nanocomposites Used for Photocatalysis of Selected Organic Dye
Z-scheme plasmonic photocatalytic Ag/AgBr/Bi2WO6 nanocomposites were synthesized by precipitation–sonochemical deposition method. X-ray powder diffraction, FTIR spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and UV-vis diffuse reflectance spectroscopy were used to certify the coexistence of spherical Ag and AgBr nanoparticles randomly supported on the surface of orthorhombic Bi2WO6 nanoplates. In this research, the visible absorption of Ag/AgBr/Bi2WO6 nanocomposites was better than that of pure Bi2WO6 and AgBr/Bi2WO6 samples because of the synergistic effect of surface plasmon resonance (SPR) of metallic Ag nanoparticles and Z-scheme Ag/AgBr/Bi2WO6 heterojunctions. Photocatalytic activity and mechanism of ternary Ag/AgBr/Bi2WO6 photocatalyst were investigated under visible light illumination and discussed in details according to the experimental results.
