摘要：

The water splitting under visible light irradiation has been achieved by the Z-scheme system constituted of an Fe3+/Fe2+ redox couple as an electron relay and two powdered heterogeneous photocatalysts which we have recently developed. The (Pt/SrTiO3:Rh)-(BiVO4) system showed the highest activity with 0.3% of an apparent quantum yield at 440 nm. It can use visible light up to 520 nm.
