Abstract

A novel Bi₂O₃–Bi₂WO₆ p–n junction photocatalyst exhibits high photocatalytic activity for the degradation of organic compounds under solar/visible light irradiation, which is ascribed to the effective separation of photogenerated electrons and holes by the internal electrostatic field in the junction region.
