摘　　要：采用水热法合成MoS_(2)/ZnO复合光催化剂,通过红外光谱、X射线粉末衍射、扫描电子显微镜、紫外漫反射光谱等多种测试方法对所合成的复合材料进行结构和性能分析。结果表明,MoS_(2)/ZnO复合光催化剂中,片层结构的MoS_(2)附着在棒状ZnO表面,在可见光区复合材料的光吸收能力有一定增强。光照射120 min,MoS_(2)加入量为质量分数1.5%时,MoS_(2)/ZnO(MZ-3)催化剂对15 mg·L^(-1)四环素降解率高达90.01%,高于纯ZnO光催化剂。5次循环稳定性测试实验表明,复合催化剂具有稳定的光降解性能。MoS_(2)/ZnO composite photocatalyst was synthesized by hydrothermal method.The composition and morphology of as-prepared photocatalyst were tested by infrared spectroscopy,X-ray powder diffraction,scanning electron microscopy and UV diffuse reflectance spectroscopy.The results show that the lamellar MoS_(2)is attached to the rod-like ZnO surface,and the light absorption capacity of the composite is enhanced to a certain extent in the visible region.For light irradiation of 120 min and the mass fraction amount of MoS_(2)was 1.5%,the degradation efficiency of MoS_(2)/ZnO(MZ-3)for 15 mg·L^(-1)tetracycline was up to 90.01%,which was higher than that of pure ZnO.Five cycle stability test experiments showed the stable photodegradation performance of the composite catalyst.
