Abstract

BiVO4 nanofibers were prepared by electrospinning, and Ag/BiVO4/BiPO4 heterojunction photocatalysts were successfully synthesized by hydrothermal method and UV irradiation. XRD, SEM, TEM, XPS, EIS, PL and BET characterized their structures and optical properties. The results of visible photodegradation of tetracycline (TC) for 60 min showed that the sample AgBVPO-2 had high photocatalytic performance. The visible light catalytic efficiency of the Ag/BiVO4/BiPO4 composite photocatalyst is 9.2 times and 1.6 times that of the single-component BiPO4 and BiVO4, respectively, and 9.44% higher than that of the BiVO4/BiPO4 composite photocatalyst. After 10 catalytic experiments, the photocatalytic activity of the Ag/BiVO4/BiPO4 heterojunction did not decrease significantly, indicating that the Ag/BiVO4/BiPO4 heterojunction was stable. Free radical capture experiments show that ·O2− and h+ are the main groups involved in the redox reaction. In addition, Ag/BiVO4/BiPO4 heterojunction photocatalysts also have good catalytic effects on Rhodamine B (RhB), methylene blue (MB) and crystal violet (CV).
