C/g-C₃N₄ was firstly prepared by thermal condensation method with urea and glucose as precursors, and then C/g-C₃N₄/MoS₂ ternary composites were synthesized by solvothermal method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), N₂ adsorption-desorption, ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), photoluminescence spectroscopy (PL) and transient photocurrent analytical tests were used to characterize the crystal structure, morphology, specific surface area and optical properties of photocatalysts. In comparison with the C/g-C₃N₄, the ternary composites not only present a larger specific surface area, stronger light absorption capacity, but also were more favorable for electron transfer. At the same time, the performance of visible light catalytic degradation of methyl orange was studied. It was found that C/g-C₃N₄/MoS₂-2.0% (Mass fraction of MoS₂: 2.0%) showed the highest reaction rate constant (0.008 6 min^-1), which was 5.7 times and 2.3 times of g-C₃N₄/MoS₂ 2.0% (0.001 5 min^-1) and C/g-C₃N₄ (0.003 6 min^-1), respectively.
