%X 本文采用超声分散方法制备WS2/TiO2复合物，在光照条件下，对罗丹明B的降解效果进行了一系列研究。在确定WS2与TiO2的混合比例后，同时又对WS2/TiO2煅烧温度、煅烧时间、催化剂的用量、光照时间、光照功率、染料浓度等影响因素分别进行了讨论。实验结果表明，催化剂的量为1.00 g/L、染料的初始浓度为10.00 mg/L，WS2/TiO2(1:11)、焙烧温度为350 °C、焙烧时间为90 min时，对罗丹明B染料的降解效果最佳。<br>WS2/TiO2 composite was prepared by using the ultrasonic dispersion method, and the effect of degradation of Rhodamine B was studied under irradiation conditions. The influence factors on the degradation efficiency, such as calcination temperature and time of WS2/TiO2 , the amount of catalyst, illumination time, irradiation intensity, and initial concentration of Rhodamine B were discussed, respectively. The experimental results revealed that the best degradation efficiency of Rhodamine B based on the amount of catalyst was 1.00 g/L, the initial concentration was 10.00 mg/L, the m(WS2):m(TiO2) was 1:11, and the calcination temperature and time were 350 °C and 90 min, respectively
