Abstract：

This　work　shows　a　novel　artificial　donor–catalyst–acceptor　triad　photosystem　based　on　a　mononuclear　C5H5-RuH　complex　oxo-bridged　TiO2hybrid　for　efficient　CO2photoreduction.　An　impressive　quantum　efficiency　of　0.56　%　for　CH4under　visible-light　irradiation　was　achieved　over　the　triad　photocatalyst,　in　which　TiO2and　C5H5-RuH　serve　as　the　electron　collector　and　CO2-reduction　site　and　the　photon-harvester　and　water-oxidation　site,　respectively.　The　fast　electron　injection　from　the　excited　Ru2+cation　to　TiO2in　ca.　0.5　ps　and　the　slow　backward　charge　recombination　in　half-life　of　ca.　9.8　μs　result　in　a　long-lived　D+–C–A−charge-separated　state　responsible　for　the　solar-fuel　production.　©　2016　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
