摘要：

Herein, hydrothermally treated red phosphorus (HRP) was combined with bismuth bromide oxide (BiOBr) to construct BiOBr/HRP heterostructure composite. Regulating and optimizing the composition ratio, 7% BiOBr/HRP (The mass fraction of BiOBr in the composite was 7%) exhibited the highest photocatalytic activity, the rate constant for visible light reduction of Cr(VI) was 0.188 min(-1), which was five times higher than that of pure HRP (0.037 6 min(-1)). The heterojunction composite constructed by introducing wide band gap BiOBr into narrow band gap HRP expanded the visible spectral absorption range, enhanced the light absorption, and accelerated the separation of photo-generated electrons and holes.
