BiVO4/Bi2VO5.5 heterogeneous nanostructures with enhanced visible light photocatalytic activity were successfully prepared by a facile one-pot solvothermal method, where diethylene glycol (DEG) was used as the solvent. The as-prepared products were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectrometry (XPS) and UV-Vis absorption spectroscopy. The results revealed that the molar ratio of Bi3+ to VO43- played an important role in the formation of crystal and morphology. These BiVO4/Bi2VO5.5 heterogeneous nanostructures exhibited higher visible-light-driven photocatalytic efficiency compared to the pure BiVO4 and Bi2VO5.5. For the methyl orange (MO) degradation efficiency of BiVO4/Bi2VO5.5 heterogeneous nanostructures under visible light irradiation, about 95% of MO was degraded within 40min, which is much higher than pure BiVO4 and Bi2VO5.5. The enhancement of photocatalytic activity can attribute to the promoted light absorption capability and the separation efficiency of photo-generated electron-hole pairs.
