Abstract

We directly transformed anodized tungsten oxide film (WO ₃Â•2H ₂O) into bismuth tungstate (Bi ₂WO ₆) by substituting the intercalated water molecules with [Bi ₂O ₂] ²⁺ in a hydrothermal treatment. The resultant Bi ₂WO ₆ was readily used as an electrode to produce anodic photocurrent in H ₂ evolution on the Pt counter electrode observed under visible light irradiation.
