摘要

Flower-like Bi5O7 I microspheres modified with Ag nanoparticles are prepared, exhibiting excellent surface plasmon resonance. Bi5O7 I/Ag/acrylate fluoroboron polymer (AFBP) ternary assembly films are also fabricated using Bi5O7 I/Ag composites uniformly distributed in acrylate fluorobomn polymer. The structure and photocatalytic properties of Bi5O7 I/Ag are characterized. Characterization results indicate that Bi5O7 I/Ag has a large specific surface area, a low band gap, and excellent visible light response. To evaluate the properties of the Bi5O7 I/Ag/AFBP ternary assembly film, laboratory diatom assays and antibacterial activity are tested. The results show excellent diatom anti-settlement performance and high antibacterial rates of 99.63% for Escherichia coli and 99.92% for Staphylococcus aureus. Photocatalytic degradation of 2,4,6-trichlomphenol by visible-light irradiation for 150 min shows a removal rate of 95%, which is attributed to charge efficiency separation. Simultaneously, the photodegradation pathway and TOC of 2,4,6-trichlorophenol are analyzed. Thus, this study shows the significance of assembly film for potential marine applications in the future.
