摘　　要：用共沉淀法合成了以钴为主的水滑石型化合物（ＨＴＬｃ），用ＸＲＤ、ＩＲ等对其及热分解产物进行了表征．结果表明，水滑石经过焙烧，逐渐失去层间的Ｈ２Ｏ、ＯＨ－和ＣＯ２－３，转化成尖晶石结构．比表面积测定和ＣＯ２－ＴＰＤ结果表明，焙烧温度和产物的Ｃｏ∶Ｃｕ比对表面积和碱性均有明显的影响．The hydrotalcitelike compounds CoMAlCO3(HTLc,M=Cu2+,Ni2+,Mn2+,Cr3+,Fe3+) were synthesized by coprecipitation method and characterized by XRD and IR measurements. The results showed that the interlayer H2O and OH- and CO2-3 in the compounds were lost with the increase of the calcination temperature, with the structure of the compounds being changed into spinel structure. The CO2 TPD results showed that the calcination temperature and Co/Cu ratio of the compounds had an obvious effects on the surface area and the alkalinity of the products.
