Abstract
- Herein, we report the synthesis of novel narrow band gap phosphorus sulfide quantum dots (PSQDs)‐modified bismuth oxybromide (Bi24O31Br10) heterojunction (noted as BOB/PS) for the highly efficient photo‐degradation of hazardous organic pollutants including rhodamine B (RhB), methyl orange (MO), and malachite green (MG). Such a high photocatalytic activity of BOB/PSQDs heterojunction derives from the improved visible‐light response capacity, high surface area/pore volume, and suitable band structure for efficient electron transfer to generate reactive oxygen species (ROS). ROS trapping experiments demonstrate that hydroxy (⋅OH) and superoxide radicals (⋅O2−) play important roles in the photo‐degradation. A possible S‐scheme mechanism for the enhanced photocatalytic activity of BOB/PS is proposed. [ABSTRACT FROM AUTHOR]
