- Abstract
In this paper, we have successfully prepared an organic-inorganic hybridized Keggin-type Ruthenium-containing polytungsten oxide clusters that combines the organic ligand 2,2’-bipyridine (2,2’-bpy with the noble metal ruthenium, formulated as H3[{Ru (H2O) (bpy) }2O(PW11O39)]·10H2O. Title compound inherited the strong absorption in the visible and UV regions, providing a good basis for photocatalysis. The experimental results showed that it exhibited good photocatalytic activity in the visible-light-driven reduction of nitrobenzene using N2H4·H2O as a reductant with a yield of 98.1%(turnover number is 322.5, turnover frequency is 53.75 h-1). Three cycles of experiments indicated that this compound was an effective and stable heterogeneous catalyst.
