A novel Bi-based layered photocatalyst BaBiO2Br was successfully prepared by a solid-state reaction. The as-prepared samples were characterized by XRD, SEM, DRS, PL and FT-IR. The calcination temperature was found to play an important role in controlling synthesis of BaBiO2Br, and pure BaBiO2Br can only be obtained at 800–900°C. BaBiO2Br with an indirect optical band-gap of 2.93eV possess photoabsorption...
A novel visible-light-driven Bi-based layered photocatalyst Bi4NbO8Br was successfully prepared by a solid state reaction. The calcination temperature was found to play an important role in controlling synthesis of Bi4NbO8Br, and pure Bi4NbO8Br can only be obtained at 700°C–800°C. The as-prepared samples were characterized by XRD, SEM, DRS and PL. Bi4NbO8Br has an indirect-transition optical band-gap...
