Synthesis and Characterization of Co-Mg-Al-Cr Hydrotalcite-like Compounds

In this paper,the samples of Mg-Al-Cr,Co-Mg-Al,and Co-Mg-Al-Cr hydrotalcite-like compounds(HTLcs) were prepared by using coprecipitation method.And the samples were studied by X-ray diffraction(XRD),differential scanning colourimetry(DSC),and Brunner-Emmett-Teller method(BET).The result showed that all the precursors formed the structure of HTLcs.
