Synthesis of a novel one-dimensional BiOBr–Bi₄O₅Br₂ heterostructure with a high quality interface and its enhanced visible-light photocatalytic activity

Abstract

A novel rod-like BiOBr–Bi₄O₅Br₂ heterostructure with a high quality interface is synthesized by calcining a BiOBr precursor in air. The BiOBr–Bi₄O₅Br₂ heterostructure exhibits outstanding photocatalytic activity for degrading RhB dyes at high concentrations under visible/solar light irradiation.
