The layered compound of lead bismuth oxybromide PbBiO{sub 2}Br, prepared by conventional solid-state reaction method, has an optical band gap of 2.3 eV, and possesses a good visible-light-response ability. The references, PbBi{sub 2}Nb{sub 2}O{sub 9}, TiO{sub 2-x}N{sub x}, BiOBr and BiOI{sub 0.8}Cl{sub 0.2}, which are excellent visible-light-response photocatalysts, were applied to comparatively understand the activity of PbBiO{sub 2}Br. Degradation of methyl orange and methylene blue was used to evaluate photocatalytic activity. The results show that PbBiO{sub 2}Br is more photocatalytically active than PbBi{sub 2}Nb{sub 2}O{sub 9}, TiO{sub 2-x}N{sub x} and BiOBr under visible light. - Graphical abstract: The as-prepared layered PbBiO{sub 2}Br with an optical band gap of 2.3 eV possesses a fair visible-light-response ability.
