摘要：利用共沉淀法合成苯甲酸根插层镁铝水滑石,并在温度为800℃时对插层水滑石进行焙烧;采用X射线衍射、红外光谱、透射电子显微镜、扫描电子显微镜、X射线能量色散谱等分析手段对制得的样品进行表征。结果表明,800℃焙烧后的样品出现卷曲得较完整的纳米管状结构,平均管长约为10μm,管径约为1μm。

Abstract： Benzoate intercalated magnesium aluminum layered double hydroxides was prepared by the method of co-precipitation. The intercalated layered double hydroxides was calcined at the temperature of 800 ℃ . The structure and morphology of the prepared samples were analyzed by XRD， IR， TEM， SEM and EDS. The results show that completely curly oxide nano-tubes with mean length of about 10 μm and diameter of about 1 μm are obtained through the calcination process at the temperature of 800 ℃.
