| titleOfInvention | Iron oxide/bismuth tungstate composite photocatalyst, preparation method thereof and application thereof |
| abstract | The invention discloses an iron oxide/bismuth tungstate composite photocatalyst, a preparation method of the iron oxide/bismuth tungstate composite photocatalyst and the application of the iron oxide/bismuth tungstate composite photocatalyst. The iron oxide/bismuth tungstate composite photocatalyst has a Fe2O3/Bi2WO6 XRD (X-ray diffraction) diffraction pattern as shown in Figure 1 of the specification and a composite morphology as shown in Figure 2 of the specification. 10-30nm of Fe2O3 nano-particles are precipitated on the surface of Bi2WO6 by a soaking-low temperature roasting technology. The invention represents the change of the structure, the morphology, the ultraviolet-visible absorption spectrum and the fluorescence spectrum of the material before and after being modified in details, and researches the catalytic degradation of the visible light of the iron oxide/bismuth tungstate composite photocatalyst to the activity of the dyestuff rhodamine B (RhB). The result shows that Fe2O3 particles with the mean grain sizes of 20nm are dispersed on the surface of a nanosheet unit of a Bi2WO6 superstructure, the visible light response range of the Fe2O3/Bi2WO6 composite photocatalyst is obvious in bathochromic shift, and the composition probability of photon-generated carriers can be effectively restrained as well. When the toasting temperature is low temperature of 200DGE C, and the Fe element content is 0.1% (wt%), the photocatalytic activity is optimal, and the efficiency of the visible-light catalytic degradation RhB can be improved by 20% compared with that of the un-composited visible-light catalytic degradation RhB. |
