| Abstract: | A novel visible-light-driven layered photocatalyst of Bi-based PbBiO2Cl is prepared by solid-state reaction. The optical band gap of PbBiO2Cl is determined to be 2.45 eV by UV–vis diffuse reflectance spectroscopy. Generally, the photocatalytic activity for degrading methyl orange (MO) over PbBiO2Cl is higher than that over anatase-type TiO2 under UV light and visible light illumination. The RuO2 loading over PbBiO2Cl leads to an obvious increase in photocatalytic performance. The internal electric fields between [PbBiO2] and [Cl] slabs are considered to be useful for the efficient separation of electron–hole pairs upon photoexcitation. |
