| 摘 要： | 以脱脂棉为模板,以四水乙酸镁和九水硝酸铝为前驱物,采用外模板法制备了一系列Al2O3-MgO混合氧化物,并用X射线衍射、扫描电镜、低温N2吸附等手段对其进行了表征.结果表明,所制样品显示出棉纤维的生物形态,且具有较高的比表面积(可达206 m2/g).Mg含量较低时Al2O3-MgO混合氧化物为无定形结构,当Mg/Al...

| Abstract: | A series of Al2O3-MgO mixed oxide samples were prepared via an exotemplating pathway using degreasing cotton as template and magnesium acetate and aluminum nitrate as MgO and Al2O3 precursors,respectively. The resulting solid acid/base bifunctional material samples were characterized by X-ray diffraction,scanning electron microscopy,and nitrogen adsorption. It was found that these as-prepared Al2O3-MgO material samples replicated the biomorph of cotton fibre and represented high specific surface area(206 m2... |
