In this work, Ag 3 PO 4 nanoparticles were successfully decorated on graphene-like MoS 2 sheet by one-pot hydrothermal method. Field-emission scanning electron microscopy (FE-SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), Photoluminescence (PL), and Fourier transform infra-red (FT-IR) spectroscopy techniques were employed for the characterization of the prepared sample. The as-synthesized Ag 3 PO 4 decorated MoS 2 (Ag 3 PO 4 /MoS 2 ) composite exhibited higher visible-light photocatalytic activity and stability toward the degradation of methylene blue (MB) in aqueous solution, as compared to Ag 3 PO 4 particles and pristine MoS 2. The high photocatalytic stability is due to the successful inhibition of the photocorrosion of Ag 3 PO 4 by transferring the photogenerated electrons of Ag 3 PO 4 to MoS 2.
