[en] In this study, the successful construction of a novel AgVO₃/BiVO₄ heterojunction photocatalyst via a facile two-step method was reported. The organic dye Rhodamine B (RhB) was chosen as a simulative pollutant to investigate the photocatalytic performances of the samples. The results showed that the AgVO₃/BiVO₄ heterojunction possessed remarkably enhanced photocatalytic activity under visible-light irradiation compared with individual components. The AgVO₃/BiVO₄ heterojunction possessed the highest rate constant, which was about 17.2 and 3.1 times higher than those of pure BiVO₄ and AgVO₃, respectively. Such an enhancement was mainly ascribed to the formation of suitable heterojunction structure with intimate interfacial contact between AgVO₃ and BiVO₄, resulting in the effective separation of photogenerated electron-hole pairs. The possible photocatalytic mechanism was also proposed based on the trapping experiments of active species, indicating that h⁺ and ^·OH played a key role in the photocatalytic degradation process. - Highlights: • A novel AgVO₃/BiVO₄ heterojunction has been synthesized by a facile method. • The AgVO₃/BiVO₄ shows enhanced visible-light-driven photocatalytic activity. • The improved separation efficiency of photogenerated carriers is the main reason. • Our findings can offer useful insights for development of efficient photocatalysts.
