SYNTHESIS AND CHARACTERIZATION OF NEW MOLYBDENUM PHOSPHORUS COMPOUND SUBSTITUTED BY ZINC

本文合成了具有Keggin型取代磷钼多金属氧酸盐[Bu_4N]_4H_3[(PMo_(11)ZnO_(40)],并通过C、H、N、P、Zn、Mo等元素的分析、红外光谱分析、X-射线粉末衍射分析、TG-DTA-DSC等测试方法研究了它们的组成、晶体结构、光谱性质及热稳定性质,初步探索了合成条件对产物的影响,确认所合成的Zn取代多金属氧酸盐结构为Keggin型。

Polyoxometalate substituted by Keggin-type phosphomolybdate,polyoxometalate[（Bu）4N]4H3[（PMo（11）ZnO（40）]was synthesized.Testing methods such as IR,C,H,N elemental analysis and P,Zn,Mo and other elements analysis,XRD,TG-DTA-DSC were used to analyze the materials＇ composition,crystal structure,spectroscopic properties and thermal stability.The synthesis conditions on the impact of the final product were also preliminarily explored.It is confirmed that the structure has such polyoxometalate substituted by Zn was Keggin-type.
