| Abstract: | The layered compound of lead bismuth oxybromide PbBiO2Br, 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, PbBi2Nb2O9, TiO2−xNx, BiOBr and BiOI0.8Cl0.2, which are excellent visible-light-response photocatalysts, were applied to comparatively understand the activity of PbBiO2Br. Degradation of methyl orange and methylene blue was used to evaluate photocatalytic activity. The results show that PbBiO2Br is more photocatalytically active than PbBi2Nb2O9, TiO2−xNx and BiOBr under visible light. |
