A hybrid for visible-light-driven photocatalytic reduction of CO2 with methanol as a reductant was constructed by combining two different types of photocatalysts, i.e, a Ru(II) dinuclear complex for CO2 reduction adsorbed on Ag-loaded TaON (TaON-Ag ) for oxidation of methanol. The isotope experiments clearly showed that this hybrid photocatalyst mainly produced HCOOH from CO2 and HCHO from methanol. The photocatalytic reaction proceeds via stepwise excitation of both TaON-Ag  and the Ru dinuclear complex on TaON-Ag  like the Z-scheme of photosynthesis of green plants.
