三维Bi2WO6-Fe2O3复合材料光催化高效降解环丙沙星

Photocatalytic Degradation of Ciprofloxacin by Three-Dimensional Bi2WO6-Fe2O3 Composite

以Fe2O3作为诱导剂,通过水热法合成Bi2WO6-Fe2O3复合材料对环丙沙星进行光催化降解。同时,采用SEM,TEM,XRD及XPS对材料进行表征,测试结果表明Bi2WO6-Fe2O3为3D玫瑰花构型,Bi2WO6负载于Fe2O3纳米片上。在相同光照条件下,Bi2WO6-Fe2O3,Bi2WO6及Fe2O3的环丙沙星降解率分别为100%,88.1%和39.1%,表明Fe2O3的加入可以有效提高Bi2WO6的光催化活性。

In this study,Fe2O3 was used as the inducer to synthesize Bi2WO6-Fe2O3 composite by the hydrothermal method for the photocatalytic degradation of ciprofloxacin.Meanwhile,the properties of Bi2WO6-Fe2O3 composite were characterized by SEM,TEM,XRD and XPS.The results showed that Bi2WO6-Fe2O3 was a 3D rose structure,and Bi2WO6 was loaded on Fe2O3 nano chips.Under the same light condition,the degradation rates of ciprofloxacin by Bi2WO6-Fe2O3,Bi2WO6 and Fe2O3 are 100%,88.1%and 39.1%,respectively,which shows that the addition of Fe2O3 could effectively improve the photocatalytic activity of Bi2WO6.
