- Abstract
As a visible-light response semiconductor materials, bismuth vanadate (BiVO
4 ) is extensively applied in photodegradation organic dye field. In this study, we synthesized C3 N5 nanosheets and coupled with decahedral BiVO4 to construct a Z-scheme C3 N5 /BiVO4 heterostructure with close interface contact. By introducing C3 N5 into BiVO4 , 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 BiVO4 and C3 N5 . The accelerated separation of charge carriers ensures C3 N5 /BiVO4 heterostructures with a powerful oxidation capacity compared with pure BiVO4 . Due to the synergistic effect in Z-scheme heterostructure, the C3 N5 /BiVO4 demonstrated an improved photodegradation ability of rhodamine B (RhB) and methylene blue (MB) that of bare BiVO4 ., (© 2024.
