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
