In this work, a series of hydrogenated titanium dioxide (H-TiO 2 -20, H-TiO 2 -40, H-TiO 2 -60) were synthesized by calcining P25, and H-TiO 2 -40/MoS 2 composites were prepared by hydrothermal method. Then, the morphology, composition and optical properties of the synthesized samples were analyzed by XRD, SEM, PL and other characterization methods. The photocatalytic degradation experiments of tetracycline (TC) and methyl0ene blue (MB) under visible light irradiation showed that the catalytic performance of H-TiO 2 -40 sample was significantly better than that of P25, and the degradation efficiency of MB by H-TiO 2 -40/MoS 2 reached 92% within 2.5 h, which was 1.32 times that of pure H-TiO 2 -40. In addition, the degradation rate of MB by H-TiO 2 -40/MoS 2 still reached 88% after four recycling tests.
