摘要
报道了通式为K1 0 H5[Ln(PMo5W4V2 O3 9) 2 ]·nH2 O (Ln =La ,Ce ,Pr ,Nd ,Eu ,Gd ,Dy)的 7种五元新型杂多配合物的合成方法。从IR ,UV ,3 1 P ,51 VNMR ,X射线粉末衍射证实产物仍保持Keggin结构 ,借助TG DTA、变温IR、XRD和水溶性实验考察了新配合物热解性质 ,得出了热稳定的温度范围为 5 0 0~ 5 5 0℃。该系列配合物对H2 O2 的分解具有一定的催化作用 ,且不同稀土配合物对H2 O2
The synthesis of seven new type heteropoly complexes of general formula K 10 H 5[Ln(PMo 5W 4V 2O 39 ) 2· n H 2O (Ln=La, Ce, Pr, Nd, Eu, Gd, Dy) were reported. The results of IR, UV, 31 P NMR, 51 V NMR and XRD spectroscope demonstrate that the products still maintain Keggin structur. Their thermal stabilities studied by water solubility test, TG DTA, IR and XRD at various temperature show that the pyrolysis temperature is in the range of 500~550 ℃. This series of complexes have good catalytic activity for decomposition of hydrogen peroxide.
