摘要：

An ultrasound-assisted, precipitation-deposition method has been developed to synthesise visible-light-responsive BiOBr-ZnFe2O4 heterojunction photocatalysts. The heterojunctions with suitable BiOBr/ZnFe2O4 ratios have a fascinating micro-spherical morphology and exhibit exceptional photocatalytic activity in visible-light degradation of Rhodamine B.
