Investigation of band offsets of interface BiOCl:Bi2WO6: a first-principles study.

Density functional theory calculations are performed to study the band offsets at the interface of two photocatalytic materials BiOCl:Bi(2)WO(6). It is found that the W-O bonded interface shows the most stability. An intrinsic interface fails to enhance the charge-carrier separation due to the improper band alignment between these two materials.
