摘要：

In this work, a simple co-precipitation method for the preparation of Ag2SO4@BiOCl@Bi25FeO40 (BFO) was developed. Ultraviolet-visible spectrophotometric analysis, X-ray diffraction patterns, Fourier transform infrared spectroscopy (FT-IR), and scanning field emission electron microscopy (FESEM) were performed to characterize the newly synthesized nanocomposite. In addition, the EDX method was used to determine the actual material quantities. The synthesized samples of Bi25FeO40 and Ag2SO4 Bi25FeO40 showed high absorption in the visible region. Furthermore, the photocatalytic activity was significantly improved by the addition of Ag2SO4. The results showed photcatalytic efficiency was reached to about 99% with 0.01 g of Ag2SO4@BiOCl@Bi25FeO40 in pH 4 under visible light. The isoelectric pH of the photocatalayst was obtained 5. Also, kinetic study showed a first order mechanism for photodegradation. Moreover, a mechanistic study was proposed for the newly synthesized heterostructures.
