Abstract

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.
