Bi/BiVO4/V2O5 has been successfully synthesized by a simple annealing of BiVO4 in Ar/H2. The obtained Bi/BiVO4/V2O5 was characterized by X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). The photocatalytic activities are examined by an oxygen-evolution reaction. When BiO/BiVO4/V2O5 in air and Bi2VO5.5/ BiVO4/V2O5 in vacuum were compared with the products annealing in other atmospheres, Bi/BiVO4/V2O5 exhibited the best performance (2413 μmol·g–1·h–1), which could be attributed to the synergistic combination of Bi, BiVO4, and V2O5. This study may open up a new avenue for the development of an efficient composite photocatalyst.
