(WO3·2H2O) 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 H2 evolution on the Pt
counter electrode observed under visible light irradiation.
