　　BiOI/Bi2WO6 nanocomposite photocatalyst were synthesized via a one-step hydrothermal method.X-ray powder diffraction and Raman spectroscopy analyses confirm the presence of BiOI and Bi2WO6 as main phases in the composite photocatalyst.A gradual increase in the BiOI content of the composite photocatalyst results in an obvious red-shift of the absorption edge from ca.450 nm to longer wavelengths up to ca.700 nm.
