Abstract

BiOI/Bi₂MoO₆ heterostructures with different amounts of BiOI were successfully prepared via a facile deposition method. The obtained BiOI/Bi₂MoO₆ photocatalysts exhibited much higher visible light (λ > 420 nm) induced photocatalytic activity compared with single Bi₂MoO₆ and BiOI photocatalysts. 20 % BiOI/Bi₂MoO₆ nanocomposite exhibited the highest photocatalytic activity with almost all RhB decomposed within 70 min. However, excess BiOI covering on the surface of Bi₂MoO₆ can inversely reduce the photocatalytic activity. The enhanced photocatalytic activities could be resulted from the function of the novel p–n heterojunction interface between Bi₂MoO₆ and BiOI, which could separate photoinduced carriers efficiently. Possible mechanisms on the basis of the relative band positions were also discussed.
