Abstract:
      The g-C3N4/MoS2 nanosheets were prepared via a facile ball milling method. The composite photocatalysts were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), UV–vis diffuse reflectance spectroscopy (DRS) and photoluminescence (PL) spectroscopy. The results indicated that MoS2 nanosheets were successfully coupled into the g- C3N4 to form C3N4/ MoS2 heterojunction. The photocatalytic activities were evaluated by degradation of organic Rhodamine B (RhB) under visible light irradiation. The kinetic constant of RhB degradation with g-C3N4/MoS2 nanosheets-2 wt % heterojunction (0.0368 min?1) is about 4.3 as high as that of the bulk g-C3N4 (0.00840 min?1). The enhanced photocatalytic activities can be mainly ascribed to the efficient separation and transportation of photo-induced electron-hole pairs. The possible photocatalytic mechanism of composites was proposed according to the light trapping experiment.
