钴铁水滑石的合成及表征
The synthesis and characterization of cobalt-iron hydrotalcite-like compounds
【摘要】 以Co(NO3)2·6H2O和Fe(NO3)3·9H2O为原料,以NaOH和Na2CO3为沉淀剂合成了一系列钴铁水滑石,通过XRD,IR,TG-DTA,ICP等手段对样品进行测试和表征,X衍射结果显示,其理想构型的Co/Fe摩尔比为2～5.
【Abstract】 A series of Co-Fe hydrotalcite-like compounds have been synthesized by combining a mixed solution of Co（NO3）2·6H2O,Fe（NO3）3·9H2O with a second solution containing NaOH and Na2CO3. The compounds have been characterized by XRD,IR,TG-DTA,and ICP. The results showed that the hydrotalcites with Co/Fe molar ratios of 2 to 5 have the nice crystal form and high purity.
