摘　　要：用模板法制备铁/镱共掺杂二氧化钛空心球(Fe/Yb-TiO2HS),使用扫描电子显微镜(SEM)观察和X射线衍射(XRD)、X射线光电子能谱(XPS)、傅里叶红外光谱(FT-IR)、热失重(TG)等测试方法对对其进行了表征。使用浓度为20 mg/L的甲基橙溶液模拟废水,研究了铁/镱共掺杂二氧化钛空心球的催化性能。结果表明:铁/镱共掺杂的二氧化钛空心球对甲基橙的降解效果较好,铁掺杂量为0.1%和镱掺杂量为1%的催化剂其光催化性能达到92.57%。Composites of Fe/Yb co-doped TiO2 hollow spheres(Fe/Yb-TiO2HS)were prepared by template method and then characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),Fourier transform infrared spectroscopy(FT-IR)and thermogravimetric analysis(TG).The photocatalytic performance of the composites was assessed with a simulated wastewater of 20 mg/L methyl orange solution under radiation of visible light.The results show that the degradation efficiency of doped titanium dioxide hollow spheres for the methyl orange could be significantly improved.The composite doped with 0.1 %Fe and 1% Yb presents the optimal photocatalytic performance with degradation efficiency up to 92.57% for the methyl orange.
