摘要
用溶解-冷冻法制得K6[Zr(H2O)CoW11O39].11H2O,确定了反应的pH值和物料的最佳比.通过元素分析、离子交换、UV、IR和热重分析等方法对合成产物进行了表征.结果表明,合成产物具有Keggin结构,且具有很高的热稳定性.
The complexes K6[Zr（H2O）CoW11O39]·11H2O has been first prepared by the dissolving-cooling method. The optimal proportion of the materials and the pH of the synthesis reaction were given. The product was characterized by elemental analysis, ionic exchange, UV, IR and thermal analysis. The results show that the products possess the Keggin structure and high thermostability.
