| 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.

| Abstract: | 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/0.5Mg/Al and Co/0.5Cu/0.5Mg/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. |
