摘要：
Fe-doped Bi2O3 nanoparticles were prepared by the solvothermal method and subsequent calcination process, and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photoluminescence (PL) and UV-visible spectroscopy. XPS spectra confirmed the Fe3+ ions insert into the matrix interior of Bi2O3 nanoparticles. XRD patterns affirmed b-Bi2O3 phase did not change after Fe-doping. Compared to the pristine Bi2O3, Fe-doped Bi2O3 nanoparticles exhibited improved visible-light-driven photocatalytic efficiency for degradation of methyl orange. This result may be attributed to that Fe-doping can effectively improve the utilization of visible light and hinder the recombination process.
