摘要: The first water oxidation catalyst containing only vanadium atoms as metal centers is reported. compound the mixed-valence [(VIV5VV1)O7(OCH3)12]− species, 1. Photoinduced catalyzed by 1, in presence of Ru(bpy)32+ (bpy = 2,2′-bipyridine) and Na2S2O8, acetonitrile/aqueous phosphate buffer takes place with a quantum yield 0.20. A hole scavenging reaction between photochemically generated Ru(bpy)33+ 1 occurs bimolecular rate constant 2.5 × 108 M–1 s–1. time-resolved formation oxidized molecular 1+ reactions also evidenced for time transient absorption spectroscopy. This result opens way to use less expensive clusters catalysts artificial photosynthesis schemes.
