Abstract

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 spe ctroscopy. 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 Bi 2O3, Fe doped Bi2O3 nanoparticles exhibited improved visib le 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..
