| 摘 要： | 采用共沉淀法合成了一系列不同Co/Cr物质的量比的碳酸根型水滑石。用X－衍射、红外光谱、差热、热重、分光光度等方法对其组成和结构进行了研究。结果表明Co/Cr投料比为2到3时能形成结晶度好、纯度高的水滑石。初步推测了部分产物的组成及所含水滑石的化学式。

| Abstract: | A series of carbonate pillared Co Cr hydrotalcites by addition of different Co/Cr molar ratios were synthesized by coprecipitation.XRD?IR?DTA?TG and Spectrophotometric analysis were used to research the composition and structure of the products.The results showed that the hydrotalcites with Co/Cr molar ratios of 2 to 3 have the nice crystal form and high purity.The composition of some of the products and the formula of hydrotalcites in them are speculated preliminarily. |
