A novel Fe2O3-MoS2 nanocomposite was synthesized directly via the solvothermal method. Scanning electron microscopy (SEM) results showed the as-prepared Fe2O3-MoS2 had a uniform 3D blooming flower-like nanostructure with a MoS2 substrate. The high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) confirmed the Fe2O3 nanostructures were well-dispersed on the surface of the layered MoS2. The elemental mapping results revealed Fe, O, Mo and S elements coexisted in the Fe2O3-MoS2 nanocomposite. X-ray photoelectron spectroscopy (XPS) results displayed an S-rich MoS2 structure had been formed in the Fe2O3-MoS2 nanocomposite. As expected, the S-rich Fe2O3-MoS2 nanocomposite had better photocatalytic performance on Cr(VI) reduction than that of bare Fe2O3, MoS2 and TiO2 P25. [ABSTRACT FROM AUTHOR] |
