摘要: 用水热法合成了过渡金属联吡啶配阳离子硅钨杂多酸:[M(2,2′-bpy)2]2SiW12O40(M=Mn(1)和M=Co(2)),采用红外光谱、元素分析、热重和单晶X射线衍射对其进行了表征。 结果表明,化合物1和2是异质同构体,具有二维格子框架结构。 初步研究了2种化合物的电催化H2O析出O2性能,发现化合物1对电催化H2O析出O2有一定的催化作用。

Abstract: Two complexes of [M(2,2′-bpy)2]2SiW12O40(M=Mn(1) and M=Co(2)) have been synthesized under hydrothermal conditions and their structures were determined by using elemental analyses, IR, TG and single-crystal X-ray diffraction methods. The results showed that complexes 1 and 2 were isomorphic. The electrocatalytic activities of the two complexes toward the oxidation of H2O to O2 were preliminary evaluated. The result showed that only complex 1 has such electrocatalytic activity.

Key words: Polyoxometalate, Keggin structure, Hydrothermal synthesis
