Abstract 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.
