摘要：
SrNb2O6 powders were prepared by a conventional solid-state method and characterized by X-ray powder diffraction and UV-Vis diffuse reflection spectra. Their photocatalytic activities were investigated on the degradation of methyl orange. The results show that the photocatalytic activity of pure phase SrNb2O6 calcined at 1400 degrees C is lower than that of the impure phase SrNb2O6 calcined at 950 degrees C. The heterojunction model is used to explain that the impure sample can improve the photocatalytic activity due to the interface interaction of Nb2O5 and SrNb2O6.
