In this study, the novel dual Z-scheme black phosphorus quantum dots (BPQDs)/g-C3N4/BiFeO3 photocatalyst is successfully prepared by introducing BPQDs on the surface of g-C3N4/BiFeO3 prepared by sol-gel method. The BPQDs/g-C3N4/BiFeO3 reveals remarkable enhanced photocatalytic degradation efficiency of methyl violet (MV) compared with pure BiFeO3. The enhanced photocatalytic performance is attributed to the effective separation of photogenerated carriers of dual Z-scheme electrons transfer channels. The possible electrons transfer mechanism of dual Z-scheme photocatalytic system is proposed. This work also emphasizes the essential role of dual Z-scheme photocatalytic system in the environment pollution. (C) 2020 Published by Elsevier B.V.
