Anderson结构钼系过渡金属稀土盐的合成与性质研究
Synthesis and properties for the rare earth salt of molybdenum series transition metals with Anderson structure
【摘要】 首次合成了具有Anderson 结构的稀土元素钼系化合物,通式为Ln[XMo6O24H6]·nH2O(Ln = La,Ce,Pr,Nd,Gd;X= Cr( Ⅲ) ,Co( Ⅲ) ,Ni( Ⅱ) ,Zn( Ⅱ) ;n =7 ~10) ,此类化合物属Anderson 结构的B型,其特点是杂原子与6个—OH 相连形成八面体.通过ICP,IR,UV,CV 等方法对产物的性质进行了表征.电化学实验结果表明:杂原子为Co( Ⅲ) 的稀土盐对玻碳电极的表面有修饰作用.
【Abstract】 Lanthanides molybdenum compound, Ln[XMo 6O 24 H 6]· n H 2O(Ln=La,Ce,Pr,Nd,Gd;X=Cr(Ⅲ),Co(Ⅲ),Ni(Ⅱ),Zn(Ⅱ); n =7~10), has firstly been synthesized. It belongs to the B-type of Anderson structure in which the heteroatom is coordinated by six — OH form octahedra. They were characterized by ICP,IR,UV,CV method, etc. The result of electrochemical experament shows that Co(Ⅲ) salt has an action of modification to the surface of G.C. electrode.
