摘　　要：通过煅烧P25合成系列氢化二氧化钛(H-TiO_(2)-20、H-TiO_(2)-40、H-TiO_(2)-60),利用水热法制备出H-TiO_(2)-40/MoS_(2)复合光催化剂,并通过XRD、XPS、SEM、PL等对合成样品的形貌、组成以及光学性质进行了分析表征.在可见光辐照下,以四环素(TC)、亚甲基蓝(MB)为目标污染物的光催化降解实验表明,H-TiO_(2)-40样品的催化性能明显优于P25,而且H-TiO_(2)-40/MoS_(2)对MB的降解效率在4 h内达到92%,是纯H-TiO_(2)-40的1.32倍.另外,在4次循环光催化实验中,H-TiO_(2)-40/MoS_(2)对MB的降解率仍达到88%.In this article,a series of hydrogenated titanium dioxide(H-TiO_(2)-20,H-TiO_(2)-40,H-TiO_(2)-60)was synthesized by calcining P25,and H-TiO_(2)-40/MoS_(2) composite photocatalyst was prepared by hydrothermal method.Then,the morphology,composition and optical properties of the synthesized samples were analyzed by XRD,XPS,SEM,PL and other characterization methods.The photocatalytic degradation tests of tetracycline(TC)and methylene blue(MB)under visible light showed that the catalytic performance of H-TiO_(2)-40 was better than that of P25,and the degradation efficiency of MB by H-TiO_(2)-40/MoS_(2) was 92%within 4 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 cycles of photocatalytic experiments.
