Abstract

Although Bi3O4Cl is a kind of semiconductor catalyst driven by visible light, which possesses a layered structure and high chemical stability; however, the fast recombination of electron–hole pairs still limits its photocatalytic activity. In this work, the heterojunction combined Bi3O4Cl and Bi4NbO8Cl with a particle size of about 30–70 nm is constructed by a solid-state reaction method to improve the photocatalytic performance. XRD, TEM, XPS, and some other measurements are used to characterize the structure, morphology, and optical properties of the samples. Compared with Bi3O4Cl, the Bi3O4Cl/Bi4NbO8Cl Z-scheme photocatalyst shows a better photocatalytic performance, with 80% removal for ciprofloxacin (CIP) and 78% for bisphenol A (BPA) after 3-h illumination.
