摘要: 报道了钴取代的钼硅稀土二电子杂多蓝Ln2H2[SiMo11Co(H2O)O39]·nH2O,(Ln=La,Ce,Pr,Nd,Sm,Gd)的制备和离析方法,并通过元素分析、红外光谱、紫外-可见光谱、循环伏安、热重-差热分析、X射线光电子能谱、电子顺磁共振、29Si核磁共振和磁化率等对产物进行了表征及性质研究.结果表明,杂多蓝的结构与其母体杂多酸相比,结构上发生轻微的畸变,还原过程中,Co2+及Ln3+均未变化.

Abstract: Rare earth molybdosilicic heteropoly blues substituted by cobalt, Ln2H2[SiMo11Co·(H2O)O39]·nH2O(Ln=La, Ce, Pr, Nd, Sm, Gd) have been prepared and systematically characterized by IR, UV, CV, TG DTA, XPS, 29SiNMR, polarography and magnetic susceptibility. Based on the experimental results, it is reported that the reduced products(heteropoly blues) slightly change their structures compared with unreduced compounds. Co2+and Ln3+do not change in the reduced processes.
