Bismuth trioxide and molybdenum disulfide were prefabricated by hydrothermal method.And molybdenum disulfide and bismuth oxide composites were prepared under the conditions of ultrasonic-assisted synthesis at 140℃.The samples were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM) and ultraviolet visible diffuse reflectance (DRS).The effect of the compound of molybdenum disulfide on the photocatalytic properties of bismuth iodide was explored by using methylene blue as the degraded substance.The effects of molybdenum disulfide with different mass ratios on photocatalytic activity of materials were studied.The results showed that the photocatalytic performance of 15% MoS2/BiOI composites was best.The results also showed that15% MoS2/BiOI samples showed a degradation rate of 97.09% for 100mL of methylene blue solution with a concentration of 10mg/L.
