Preparation and photocatalytic properties of Ag/BiVO4/BiPO4 heterojunction nanofibers
Source abstract
Abstract
BiVO 4 nanofibers were prepared by electrospinning, and Ag/BiVO 4 /BiPO 4 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/BiVO 4 /BiPO 4 composite photocatalyst is 9.2 times and 1.6 times that of the single-component BiPO 4 and BiVO 4 , respectively, and 9.44% higher than that of the BiVO 4 /BiPO 4 composite photocatalyst. After 10 catalytic experiments, the photocatalytic activity of the Ag/BiVO 4 /BiPO 4 heterojunction did not decrease significantly, indicating that the Ag/BiVO 4 /BiPO 4 heterojunction was stable. Free radical capture experiments show that ·O 2 − and h + are the main groups involved in the redox reaction . In addition, Ag/BiVO 4 /BiPO 4 heterojunction photocatalysts also have good catalytic effects on Rhodamine B (RhB), methylene blue (MB) and crystal violet (CV).
