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CO32-,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。

Abstract: The hydrotalcite like compounds CoMAlCO3(HTLc,M=Cu2+,Ni2+,Mn2+,Cr3+,Fe3+) were synthesized by coprecipitation method and characterized by XRD and IR measurements.The results showed that the interlayer H2O and OH- and CO32- in the compounds were lost with the increase of the calcination temperature, with the structure of the compounds being changed into spinel structure. The CO2 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.

Key words: CoCuAlCO3, hydrotalcite compound, synthesis, characterization
