Bismuth vanadate (BiVO(4)), which is a visible-light responsive heterogeneous photocatalyst, was combined with homogeneous ruthenium complexes to increase the overall photocatalytic reactivity for water oxidation with a one-electron oxidant, Co(III)(NH(3))(5)Cl. Photoinduced electron transfer from the excited state of ruthenium(II) complexes to Co(III)(NH(3))(5)Cl affords ruthenium(III) complexes which can oxidize water to oxygen with BiVO(4) under visible light irradiation.
五氯合钴(III)铵(Co(III)(NH(3))(5)Cl)是一种单电子氧化剂,将其与具有可见光响应的异相光催化剂钒酸铋(BiVO(4))相结合,可提高水氧化的整体光催化活性。在可见光照射下,钌(II)配合物的激发态将电子转移给Co(III)(NH(3))(5)Cl,生成的钌(III)配合物可在 BiVO(4)存在下将水氧化为氧气。
