摘要
采用水热法制备了具有花瓣型的ZnIn2S4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ZnIn2S4样品,为花瓣型微球状,其化学价态为Zn2+、In3+和S2-.在可见光下,研究了不同前驱体pH值、水热反应时间、合成温度下ZnIn2S4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ZnIn2S4样品对盐酸四环素具有最佳降解效果,其降解效率为76.30％.
Abstract
A petal-like photocatalyst ZnIn2S4,was prepared by the hydrothermal method.The samples were characterized by XRD,SEM,EDS and XPS analysis,confirming the successful synthesis of pure ZnIn2S4 samples in the form of petal-like microspheres with chemical valence states of Zn2+ ,In3+ and S2-.Under visible light,the degradation efficiency of ZnIn2S4 photocatalytic material on tetracycline was studied under different precursor pH values,hydrothermal reaction times and synthesis temperatures.The results showed that the petal-like ZnIn2S4 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％.
