Abstract:

The g-C3N4/MoS2 nanosheets/graphene oxide (GO) ternary composite photocatalyst was successfully prepared by a ball milling method. Its structure, morphology and optical property were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-Vis absorption spectroscopy (DRS), and photoluminescence spectroscopy (PL), respectively. The results indicated that the heterogeneous structure of MoS2 nanosheets and g-C3N4 were formed on the surface of GO. The photocatalytic activity of the photocatalyst was evaluated by degradation of organic Rhodamine B (RhB) under visible light irradiation. The ternary composite photocatalyst could degrade 96% of RhB within 120 min, about 3, 2.1 and 2.8 times higher than that of the g-C3N4, g-C3N4/MoS2 composite and g-C3N4/GO composite. Based on the experimental results and the band structure, a possible charge transfer mechanism of ternary composite photocatalyst was proposed.
