A BiOBr/Bi4MoO9 edge-on heterostructure with fast electron transport for efficient photocatalytic activity

This study demonstrates the rational design and construction of a BiOBr/Bi4MoO9 edge-on heterostructure by growing fish scale-like BiOBr nanosheets on the surface of Bi4MoO9. Such structural and compositional merits expedite electron transport and offer a large interfacial contact area and abundant reactive sites. Optimized BiOBr/Bi4MoO9 exhibited outstanding TC degradation activity.
