Degradation Effect of Super Acid Modified Fe2O3-TiO2-N on Acrylic Acid under Visible Light

doi:10.15541/jim20140234

Abstract

Abstract:

Super acid modified Fe₂O₃-TiO₂-N was prepared by hydrolysis precipitation method and sulfuric acid impregnation method. X-ray diffraction (XRD) showed that the catalysts were anatase, Fe₂O₃ were highly decentralized in the catalysts with amorphous form, and modification of SO₄^2- inhibited grain growth. Ultraviolet-visible spectra (UV-Vis) showed that Fe and N co-doping made the visible light absorption to the red shift, and sulfuric acid impregnation treatment made the light absorption to the blue shift. Diffuse reflectance Fourier transform infrared (DRIFT-IR) spectra showed that sulfuric acid impregnation can improve the surface acidity of catalysts. X-ray photoelectron spectra (XPS) showed that the valence of S was +6 in the catalysts. Its photocatalytic activity on the degradation of acrylic acid under visible light was studied. The one hour degradation rate of super acid modified Fe₂O₃-TiO₂-N catalyst under visible light was improved 57% than that of the N-doping sample under the same condition.
