Abstract

A novel AgBr/Ag₂MoO₄@InVO₄ composite photocatalyst with different heterojunction structures was successfully constructed by compounding InVO₄ with Ag₂MoO₄ and AgBr. According to the degradation, antibacterial and free radical trapping data, the photocatalytic antibacterial and antifouling activities of AgBr/Ag₂MoO₄@InVO₄ composite were evaluated, and the corresponding photocatalytic reaction mechanism was proposed. Adding AgBr/Ag₂MoO₄@InVO₄ composite, the degradation rate of ciprofloxacin (CIP) achieved 95.5% within 120 min. At the same time, the antibacterial rates of Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) achieved 99.99%. The AgBr/Ag₂MoO₄@InVO₄ composite photocatalyst showed promising usage in photocatalytic antibacterial and purification areas.
