Abstract

The Fe2O3/TNTs nanocomposites were synthesized by S.oneidensis MR-1,and the structure and property of the as-synthesized nanocomposites were characterized by high-resolution transmission electron microscope (HRTEM),X-ray diffraction (XRD),scanning electron microscopy (SEM),X-ray photoelectron spectroscopy (XPS),and ultraviolet-visible spectrophotometer (UV-Vis),respectively.The results shown that Fe2O3 was proved to successfully bonded to the surface of TiO2 (TNTs),and Fe2O3/TNTs nanocomposites had good decolorization performance for aniline blue solution under ultraviolet light.The Fe2O3/TNTs performed good photocatalytic activity which can decolor 97.5% aniline blue within 60min under ultraviolet light.The decolorization rate of Shewanellaoneidensis MR-1 combined with Fe2O3/TNTs to 80mg/L aniline blue solution was increased by 1.63% compared with pure S.oneidensis MR-1.
