Abstract

The MoS₂/Ag/AgBr composite with ultrathin-MoS₂ layers was prepared by the methods of ultrasonic liquid exfoliation and ion exchange. The composition and micromorphology of ultrathin-MoS₂/Ag/AgBr were detected by XRD, EDS, SEM and TEM in detail. The element mapping showed that the samples were well-distributed. The MoS₂ in samples and the number of plies were detected by Raman spectra specifically. The results indicated that the photocatalytic performance of the as-prepared samples would increase by 50% when the average thickness of MoS₂ was about 4 nm. The enhanced photocatalytic performance of ultrathin-MoS₂/Ag/AgBr composite is attributed to the modified conduction band of MoS₂ by reducing the layers of MoS₂ to fit the potential of O₂/O₂ ^·−. In particular, this work would expand the scope of application of MoS₂ in photodegradation.
