Abstract

A new dimer polyoxoniobate [Cu(en)₂]₁₁K₄Na₂[KNb₂₄O₇₂H₉]₂·120H₂O (1) has been synthesized and systematically characterized. Visible light photocatalytic H₂ evolution activity was researched with 1 as the visible-light photosensitizer and catalyst, cobaloximes [Co^III(dmgH)₂pyCl] as the co-catalysts, and triethylamine (TEA) as the sacrificial electron donor.
