摘要
采用共沉淀法制备了Mg/Al、Co/Mg/Al、Co/Mg/Al/Ni等类水滑石样品.应用X-射线衍射分析(XRD)、热重-差热分析(DSC)及比表面积测定(BET)等方法对所制备的类水滑石样品进行了检测和分析.实验结果表明,合成的水滑石(HT)及类水滑石(HTLCs)具有水滑石的特征衍射峰,且其混合氧化物样品的比表面与水滑石的比表面相近,说明合成的化合物基本具备水滑石的性质.
In this paper,the hydrotalcite（ HT） and hydrotalcitelike compounds（ HTLcs） of Mg / Al,Co / Mg /Al,and Co / Mg / Al / Ni were prepared by using coprecipitation method. And the samples were analyzed and studied by Xray diffraction（ XRD）,TG analysis and differential scanning colourimetry（ DSC）,and BrunnerEmmett Teller method（ BET）. The results revealed that,all the prepared precursors appeared typical characteristic diffraction peaks of hydrotalcite compounds and had the similar specific surface area,which matched the properties of hydrotalcite compounds.
