摘要:
In this study, graphene wrapped Fe-doped TiO2 (G-TiO2-Fe) spheres were prepared through a simple hydrothermal process. The structural, optical and photocatalytic properties of synthesized composite were characterized by field emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD), Raman Microprobe (Raman), X-ray photoelectron spectroscopy (XPS) and UV–Vis diffuse reflectance spectrophotometer (DRS). The G-TiO2-Fe composite showed a significant red-shift in light response edge as compared with TiO2. Meanwhile, the band gap exhi...
