Construction of S-Scheme CuS/Bi₅O₇I Heterojunction for Boosted Photocatalytic Disinfection with Visible Light Exposure.

ABSTRACT: In this paper, a novel S-scheme CuS/Bi₅O₇I heterojunction was successfully constructed using a two-step approach comprising the alkaline hydrothermal method and the adsorption-deposition method, and it consisted of Bi₅O₇I microrods with CuS particles covering the surface. The photocatalytic antibacterial effects on Escherichia coli (E. coli) were systematically examined with visible light exposure. The results suggested that the 3%-CuS/Bi₅O₇I composite showed the optimal antibacterial activity, completely inactivating E. coli (5 × 10⁸ cfu/mL) in 180 min of irradiation. Moreover, the bacterial inactivation process was scientifically described. •O₂^- and h⁺ were t
