A novel visible-light-driven Z-scheme CN/BiVO heterostructure with enhanced photocatalytic degradation performance.

As a visible-light response semiconductor materials, bismuth vanadate (BiVO) is extensively applied in photodegradation organic dye field. In this study, we synthesized CN nanosheets and coupled with decahedral BiVO to construct a Z-scheme CN/BiVO heterostructure with close interface contact. By introducing CN into BiVO, the built Z-scheme transfer pathway provides silky channel for charge carrier migration between different moieties and enables photoexcited electrons and holes accumulated on the surface of BiVO and CN.
