英文摘要	Combined adsorption and photodegradation is a promising way for fast removal of contaminants. For this aim, a black BiOBr containing Bi5+, oxygen vacancy (OV) and carbon species displays excellent adsorption and photocatalytic property is reported. The OV synergizes with carbon to enhance the production of both hydroxyl radicals (center dot OH) and superoxide radicals (center dot O-2), while grey BiOBr (G-BiOBr) with only OV can just tend to undergo oxygen reduction reaction (ORR), due to the competitive adsorption relationship between H2O and O-2. Therefore, the existence of carbon can enhances and equalizes the light-induced redox reactive oxygen species (ROS) generation reaction. FT-IR results show no organic matter characteristic peak on catalyst after photocatalysis for all samples. However, the B-BiOBr with carbon can more quickly remove contaminants from the solution than common white BiOBr (W-BiOBr) and G-BiOBr, due to the integrated adsorption and photodegradation.
