Enhanced pollutant photodegradation activity of graphitic carbon nitride on via bismuth oxyhalide graphene hybridization and the mechanism study

The Z-scheme heterojunction structure of g-C 3 N 4 and Bi 4 O 5 Br 2 adjusts the band positions of the dominant active species, providing suitable energy levels for the generation of h + and ·O 2 − , enhanced pollutant degradation.
