| 摘 要： | 用微波法制备了杂多阴离子柱撑水滑石,经XRD、IR、ESR和DTA表征,证明制备的样品具有良好的层柱结构,其热稳定性比相应的杂多酸盐提高约40℃,杂多阴离子中Cu2+并非处于标准的八面体场中,而是处于一种近似于五配位的立方锥场,并随嵌入层间后更趋于五配位。

| Abstract: | Ternary heteropoly compound was prepared by introducing cupric ion into the framework of PW12 heteropolyanion with Keggin structure. The characterization of XRD showed that the value of d001 was 1. 46 nm. The IR band of heteropolyanion was similar to that of the precausor heteropoly salt. The cupric ion in the heteropolyanion was situated in a cubic cone field with pentadentate. Its symmetry was reproduced by introducing the heteropolyanion into the hydrotalc layered region. The stability of pillared hydrotalc is higher than that of pure heteropolyanion. |
