纳米Fe-ZnO晶体光催化降解染料废水

摘要

Fe-ZnO nanocrystalline was prepared in the EtOH-H2 O solution by the NAC-FAS process,and Fe-ZnO nanocrystalline was characterized by XRD and SEM and ultraviolet-visible spectrometer with the structure and optical properties .The results show that:with the increase of Fe doping ratio ,the photocata-lytic activity of Fe-ZnO is increased , and photocatalytic activity of Fe-ZnO nanocrystalline was the best with the proportion of Fe ion is 9%.Photocatalytic activity of Fe-ZnO nanocrystalline was increased with photocatalytic degradation of methyl orange under the common action with H 2 O2 and Fe-ZnO nanocrystal-line .Fe-ZnO nanocrystalline ’ s photocatalytic properties was better than others with photocatalytic degra-dation of methyl orange when mass concentration of Fe-ZnO is 10 g/L.%采用NAC-FAS工艺在醇水溶液中制备了纳米Fe-ZnO晶体，利用XRD、SEM和UV-Vis等方法对样品的结构及光学性能进行了表征。结果表明，随着Fe掺杂比例的增加Fe-ZnO的光催化活性增加，当Fe掺杂比例为9％时的纳米Fe-ZnO晶体光催化活性最优。双氧水和纳米Fe-ZnO晶体协同作用下可以增加对甲基橙的降解率，纳米Fe-ZnO晶体的质量浓度为10 g／L时对甲基橙的降解率最佳。
