摘要
合成了通式为K_(15)H_3[Ce(P_2W_(16)VO_(61))_2]·61H_2O、K_(15)H_4[Ln(P_2W_(16)VO_(61))_2]·xH_2O(Ln=La ̄(3+),Pr ̄(3+),Nd ̄(3+),Sm ̄(3+),Eu ̄3+,Gd ̄(3+),Dy ̄(3+),Yb ̄(3+))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K_(16)[Ce(P2W(17)VO(61))2]·50H2O类似的结构,对H2O2分解有较高的催化活性。
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.
