摘要

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