摘要 通过共沉淀法制备了纳米氧化铈/氧化锌/氧化镁(CeO2/ZnO/MgO)复合光催化剂。采用X射线粉末衍射(XRD)、透射电子显微镜(TEM)、傅里叶变换红外光谱法(FT-IR)以及紫外-可见吸收光谱法(UV-Vis)对制得的纳米CeO2/ZnO/MgO进行表征,并对染料亚甲基蓝(MB)进行光催化降解。结果表明,采用共沉淀法合成的纳米CeO2/ZnO/MgO具有良好的光催化性能,在MB的初始浓度为20mg/L,CeO2/ZnO/MgO浓度为0.2g/L,紫外光照射40min条件下,对MB的降解率达到98%,紫外光照射60min条件下MB完全降解,优于相同方法合成的CeO2/ZnO。

Abstract: CeO2/ZnO/MgO nanocomposite was synthesized by a simple coprecipitation method.The nanocomposite was characterized by XRD,TEM,FT-IR and UV-Vis spectra.The photocatalytic degradation was carried out using methylene blue (MB) as the degradation target.The results showed that nano CeO2/ZnO/MgO synthesized by this method had good photocatalytic performance.When the initial concentration of MB was 20mg/L,the concentration of CeO2/ZnO/MgO was 0.2g/L and ultraviolet radiation was 40min,the degradation rate of MB reached 98%.And MB was completely degraded in 60min,which was better than CeO2/ZnO synthesized by the same method.
