Abstract: MoS2/graphene/N-TiO2 composites (MGNT) were prepared using GO, H2MoO4, (NH2)2CS, and TiN as the raw materials. The phase composition, morphology, chemical states of elements, and optical absorption performance were characte-rized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), respectively. An obvious red shift of absorption edge and enhanced intensity were observed for MGNT compared with N-TiO2(NT) and graphene/N-TiO2(GNT). The photocatalytic performance was evaluated via the photodegradation of methylene blue (MB) under visible light irradiation. The results showed that the photocatalytic performance of MGNT was 1.82 and 1.59 times of NT and GNT, respectively. In addition, the absorptivity of MGNT was 11.14 and 4.77 times of NT and GNT.
