The Enhanced Electrons and Holes Separation for Bi2MoO6/TiO2Z-scheme Heterojunction by Ag Loading

The Bi 2 MoO 6 /TiO 2 and Bi 2 MoO 6 /Ag/TiO 2 composites were solvothermally synthesized and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and (high resolution) transmission electron microscopy ((HR)TEM). The Bi 2 MoO 6 /TiO 2 and Bi 2 MoO 6 /Ag/TiO 2 composites...

Description
Summary:The Bi 2 MoO 6 /TiO 2 and Bi 2 MoO 6 /Ag/TiO 2 composites were solvothermally synthesized and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and (high resolution) transmission electron microscopy ((HR)TEM). The Bi 2 MoO 6 /TiO 2 and Bi 2 MoO 6 /Ag/TiO 2 composites exhibited higher photocatalytic activity than pure Bi 2 MoO 6 . 100% of the RhB dye molecules could be decomposed over Bi 2 MoO 6 /Ag/TiO 2 composite in 120 min. The enhanced photocatalytic activity of Bi 2 MoO 6 /TiO 2 and Bi 2 MoO 6 /Ag/TiO 2 composite was attributed to the efficient separation of photoinduced electrons and holes. The mechanism for the enhanced photocatalytic activity is discussed.
