| 摘 要： | 采用共沉淀法合成了具有不同Cu/Co/Mg比例的Cu/Co/Mg/Al四元类水滑石(HTlcs).对合成样品的结构用XRD,IR,ICP,TG-DTA进行表征分析,并与先期合成的二元类Mg/Al-HTlcs及三元类Co/Mg/Al-HTlcs进行结构差异的比较分析.XRD和IR结果表明,合成的样品均具有完整的水滑石结构且结晶度良好晶像单一,层间距由二元类(Mg/Al-HTlcs)的0.750 nm扩大到四元类(Cu/Co/Mg/Al-HTlcs)的0.785 nm.TG-DTA分析表明,合成样品的热分解过程均可分为2个阶段,其热分解温度由二元类(Mg/Al-HTlcs为250～390℃)到四元类(Cu/Co/Mg/Al-HTIcs的180～300℃)依次递减.

| Abstract: | Cu/Co/Mg/Al hydrotalcite like compounds(HTlcs)with different Cu/Co/Mg molar ratios were synthesized by coprecipitation method.The structures of the hydrotalcite materials were characterized by XRD,IR,ICP and TG-DTA,and the structure differences of the samples had been compared with as synthesized MgAl-HTlcs and CoMgAl-HTlcs.XRD and IR results show that all the materials had good crystallinity and integrated layered structure,the interlayer spacing from 0.750 nm of Mg/Al-HTlcs to 0.778 nm of Cu/Co/Mg/Al-HTlcs.TG-DTA results show that all the samples decomposed in 2 stages and the thermal stability of the hydrotalcites decreased from Mg/Al-HTlcs(250～390℃)to Cu/Co/Mg/Al-HTlcs(180～300℃). |
