摘要

•AgBr/BiOI/Bi2O2CO3 was synthesized via BiOI self-sacrifice and deposition-precipitation route.•Effect of experimental parameters on Hg0 removal was investigated in detail.•An internal electric field was generated at the heterojunction interface.•Double Z-scheme photocatalytic mechanism was elucidated.
