摘要
以无水金属氯化物为前驱体,CH2CHCH2O(C2H4O)12H为模板剂,在无水乙醇体系中合成出三维蜂窝状金属氧化物介孔材料。利用XRD、BET、TEM等手段对其进行了表征。经过400℃焙烧除去表面活性剂后,得到高质量的蜂窝状金属氧化物介孔分子筛。热稳定性好、比表面积高、孔壁晶化较好的蜂窝状金属氧化物介孔材料在催化、吸附与分离、传感器等领域有着潜在的应用价值。
Disorder (worm_like) mesoporous metal oxides were prepared using (CH_2)(CHCH_2O(C_2H_4O)_(12)H) as a template in non_aqueous solutions, for which inorganic salts serve as precursors. These mesoporous materials were characterized by XRD, TEM and BET analyses. High quality mesoporous metal oxides were obtained through calcinations removal of surfactant at 400 ℃. Worm_like mesoporous metal oxides with thermal stability, large surface areas and semicrystalline frameworks have a prospect for using in catalysis, sensors, adsorption and separation, etc.
