Abstract

Ag3PO4/MoS2 composite photocatalysts were prepared by in-situ precipitation of Ag3PO4 namoparticles on the surface of MoS2,and characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),photoluminescence (PL) and UV-Vis diffuse reflection spectrometry(UV-Vis DRS) techniques.The results showed that Ag3PO4 presented sphere-like structure with a diameter of 100~200nm,and adhered to the surface of fluff sphere-like MoS2.The photodegradation effect of Ag3PO4/MoS2 was studied by using rhodamine B(RhB) as the simulated pollutant.The results showed that the photocatalytic activity of Ag3PO4/MoS2-1% was better with RhB degradation rate of 97.95% after 60 min of visible light irradiation.The photodegradation mechanism study revealed that h+ and ·O-2 were the main active species in photodegrading RhB.Ag3PO4/MoS2 indicated high stability,as the degradation rate retained 81.03% after repeated use of the same photocatalyst for 4 times.
