Abstract
The mixed-metal sandwich-type polyoxometalate [Cd2Zn2(H2O)2(P2W15O56)2]16− (abbreviated Cd2Zn2P4W30) has been synthesized and characterized by FT-IR, 31P NMR, 113Cd NMR spectroscopies, cyclic voltammetry (CV) and elemental analysis. The electrochemical behavior of this sandwich-type complex in aqueous solution has been investigated, and also systematic comparisons of that have been made by [M4(H2O)2(P2W15O56)2]16− (M=Cd2+ and Zn2+) (abbreviated M4P4W30) and [P2W15O56]12− (abbreviated P2W15). All these compounds show successive reduction processes of the tungsten centers in a negative potential range, but in some cases, the electrochemistry involves redox reactions originating from cadmium ions. These sandwich-type complexes have efficient electrocatalytic activities towards the reduction of nitrite. However, there is a significant decrease in efficiency as the number of cadmium centers in the complex increases.
