摘要: 合成了通式为K15H3[Ce(P2W16VO61)2]·61H2O、K15H4[Ln(P2W16VO61)2]·xH2O(Ln=La3+,Pr3+,Nd3+,Sm3+,Eu3+,Gd3+,Dy3+,Yb3+)的9种镧系元素Dawson结构的钨钒磷四元杂多配合物,并用IR、UV、NMR、ESR、XRD、TG-DTA等对其结构和性质进行了研究。该类配合物具有与K16[Ce(P2W17VO61)2]·50H2O类似的结构,对H2O2分解有较高的催化活性。

Abstract: Nine tetrabasic tungstovanadophosphate heteropoly rare earth element complexeswith Dawson structure were synthesized.Their general molecular formulas are K15H4[Ln·(P2W16VO61)2]·xH2O(Ln=La3+,Pr3+,Nd3+, Sm3+,Eu3+,Gd3+,Dy3+,Yb3+).Theirstructures and properties were investigated by IR,UV,NMR,ESR,XRD,TG-DTA.Theresults showed that the series of complexes have the same structure asK16[Ce(P2W17O61)2]·50H2O.At the same time, the catalytic activity of the complexes forH2O2-decomposition was also investigated.
