摘　　要：采用水热法制备了具有花瓣型的ZnIn_(2)S_(4)光催化剂,通过XRD、SEM、EDS和XPS对样品进行了表征分析,结果表明成功合成单一ZnIn_(2)S_(4)样品,为花瓣型微球状,其化学价态为Zn^(2+)、In^(3+)和S^(2-)。在可见光下,研究了不同前驱体p H值、水热反应时间、合成温度下ZnIn_(2)S_(4)光催化材料对盐酸四环素的降解效果,试验表明在合成温度为160℃、未调pH值、保温时间为12 h条件下合成的花瓣型Zn In_(2)S_(4)样品对盐酸四环素具有最佳降解效果,其降解效率为76.30%。A petal-like photocatalyst ZnIn_(2)S_(4),was prepared by the hydrothermal method.The samples were characterized by XRD,SEM,EDS and XPS analysis,confirming the successful synthesis of pure ZnIn_(2)S_(4) samples in the form of petal-like microspheres with chemical valence states of Zn^(2+),In^(3+)and S^(2-).Under visible light,the degradation efficiency of ZnIn_(2)S_(4) photocatalytic material on tetracycline was studied under different precursor pH values,hydrothermal reaction times and synthesis temperatures.The results showed that the petal-like ZnIn_(2)S_(4) sample synthesized at 160℃without adjusting the pH value and with a holding time of 12 hours exhibited the optimal degradation performance towards tetracycline,with a degradation efficiency of 76.30%.
