摘要 以共沉淀法合成了1.5Co/0.5Cu/Al,1.25Co/0.25Cu/0.5Mg/Al,Co/0.5Cu/0.5Mg/Al和Co/Cu/Al等样品,采用TG-DSC和XRD进行了表征.结果表明,1.5Co/0.5Cu/Al,1.25Co/0.25Cu/0.5Mg/Al和Co/0.5Cu/0.5Mg/Al样品都形成类水滑石(HTLcs),而Co/Cu/Al样品因Jahn-Teller效应未能形成HTLcs. The samples of 1.5Co/0.5Cu/Al, 1.25Co/0.25Cu/0.5Mg/Al, Co/0.5Cu/0.5Mg/Al and Co/Cu/ Al were prepared by using coprecipitation method. The measured methods of XRD and TG-DSC were used to study these samples. The results indicated that 1.5Co/0.5Cu/Al, 1.25Co/0.25Cu/0.JMg/Al and Co/0.5Cu/0.JMg/ Al could form hydrotalcite-like compounds （HTLcs） while the Co/Cu/Al could not form the structure of HTLcs, likely due to the Jahn-Teller effect.
