A Z-scheme heterojunction of BON-Br-AgBr was firstly designed via simple two-step
hydrothermal-precipitation method for the enhanced photocatalytic performance. The as-prepared BON-Br-AgBr possessed an enhanced photocatalytic activity for RB-19 degradation when compared with pure BON (13.82 times), BON-Br (8.44 times) and pure AgBr (2.48 times) under visible-light, respectively. The Z-scheme heterojunction BON-Br-AgBr was proved by many techniques. And the enhanced photocatalytic performance of BON-Br-AgBr might due to some increased active sites induced by introduction of Br? and the successful construction of Z-scheme
heterojunction. Besides, the photocatalytic mechanism was also raised based on the trapping
experiments and ESR analysis
