Abstract

A novel Bi<sub>2</sub>O<sub>3</sub>–Bi<sub>2</sub>WO<sub>6</sub> 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.
