摘要: 应用电化学方法,系统研究keggin结构稀土取代衍生物Ln(MW_(11)_2(M=As,Ti,Ga,Ln=La,Ce,Pr,Nd,Sm,Eu,Gd,Dy)在溶液中的氧化还原性质,得其氧化顺序,提出还原机理。

关键词: 含钨稀土杂多化合物, Keggin结构, 氧化还原

Abstract: The redox properties of Ln(MW_(11))_2(M=As, Ti, Ga; Ln=La,ce,pr,Nd,Sm,Eu,Gd , Dy ) are systematically studied.It has been found that the redox order is La(AsW_(11))_2>La(TiW_(11))_2>La(GaW_(11))_2.The reduction process of Ln(MW_(11))_2 anion has been discussed.

Key words: Undecatungstometalate lanthanetes, Redox, Keggin structure
