The ZnIn2S4/Bi2WO6(ZlS@BW)composite photocatalyst was prepared by hydrothermal method with different temperature to solve the problems of traditional semiconductor photocatalysts,such as weak response to visible light,fast recombination of photogenerated electron-hole and weak redox ability of carrier caused by energy band structure.When the hydrothermal temperature increased from 80 ℃ to 160 ℃,the crystallization of ZlS@BW composite photocatalyst increased,the morphology became denser core-shell structure,the specific surface area and photoelectric property first decreased and then increased and the removal rate of fluvastatin gradually increased.When the temperature increased to 200 ℃,the core-shell structure was destroyed,the spe-cific surface area and photoelectric properties decreased,the degradation of fluvastatin was inhibited.The re-sults showed that the ZlS@BW composite photocatalyst prepared at hydrothermal temperature of 160 ℃ with high crystallization,compact morphology,maximum specific surface area,maximum transient photocurrent and minimum impedance radius.The excellent photocatalytic performance was also observed and 75.47％of flu-vastatin was degraded.
