摘要：
We directly transformed anodized tungsten oxide film (WO3 center dot 2H(2)O) into bismuth tungstate (Bi2WO6) by substituting the intercalated water molecules with [Bi2O2](2+) in a hydrothermal treatment. The resultant Bi2WO6 was readily used as an electrode to produce anodic photocurrent in H-2 evolution on the Pt counter electrode observed under visible light irradiation.
