摘　　要：本文以空心玻璃微珠为载体,利用溶胶-凝胶法成功制得易于回收的MoS_(2)QDs/TiO_(2)@空心玻璃微珠负载型催化剂,并对其光催化氧化降解自制模拟海水中石油醚污染的性能进行了研究。利用XRD、SEM等对催化剂材料的组分和结构进行表征,研究其在不同条件下的光催化氧化降解海水中石油醚的性能。实验结果表明,在室温(22±1℃)条件下,石油醚初始浓度为100mg/L,催化剂投加量为0.4g时,降解率可达97%。In this paper,MoS_(2)QDs/TiO_(2)@hollow glass beads supported catalyst was successfully prepared by sol-gel method with hollow glass beads as carrier,and its photocatalytic degradation of petroleum ether pollution in water was studied.The composition and structure of the catalyst materials were characterized by XRD and SEM,and the photocatalytic degradation of petroleum ether in water under different conditions was studied.The experimental results show that the degradation rate can reach 97%when the initial concentration of petroleum ether is 100mg/L and the dosage of catalyst is 0.4g at room temperature(22±1℃).
