A novel Bi-based oxybromide BaBiO2Br: Synthesis, optical property and photocatalytic activity

A novel Bi-based layered BaBiO2Br was successfully prepared by a solid state reaction at different temperature. BaBiO2Br has an indirect-transition optical band-gap of 2.93 eV and showed photodegradation of RhB under UV light and visible light irradiation.
