| Preparation of AlMSU-2 from Zeolite-like Nanoclusters: Comparison of Structural Properties and Hydrothermal Stability with Products from Other Routes | |
| 摘要: 采用含有β沸石基本结构单元的纳米簇为孔壁构造物合成了蠕虫状AlMSU-2介孔材料，并与通过直接合成和后处理嫁接途径所得的AlMSU-2进行了系统的比较研究。测试结果表明在适宜的酸度条件下，采用中性TX-100为中孔结构导向剂，以β沸石纳米簇为无机前驱物可便捷地将铝原子引入AlMSU-2骨架结构中，但目标产物并未显示出较后处理途径制得的AlMSU-2更为优越的水热稳定性。 | |

| Abstract: Mesoporous alminum-containing MSU-2 with wormhole framework was facilely prepared from preformed zeolite nanoclusters and compared with those products with similar structure synthesized by direct condensation and post-grafting methods, respectively. It is indicated that, on the basis of comprehensive characterizations, the substitution of nanosized zeolite seeds for common inorganic precursors can easily incorporate aluminum hetero-atoms into the framework structure with the aid of neutral TX-100 template under extremely acidic conditions. However, the AlMSU-2 obtained by the present route was not more hydrothermal stable than the counterpart synthesized via post-synthetic grafting method. | |
