| 中文摘要: |
| 采用γ-胺丙基三甲氧基硅烷与表面硅羟基的反应,对介孔分子筛MCM-41进行了有机胺功能化.并对其进行了表征.XRD、比表面积测定、元素分析、TG、FT-IR和TEM的测定结果均表明,MCM-41表面成功地接枝上了有机胺功能基团而六方结构特征基本保持.在有机胺功能化的MCM-41上固载Ru基催化剂,并将其用于CO2加H2合成HCOOH反应,所显示的活性优于相应的均相催化剂,并且该催化剂具有较好的回收再用性能. |
| 英文摘要: |
| The amino-functionalized mesoporous molecular sieve was prepared by using T-aminopropyltrimethoxysilane to react with MCM41. The results of XRD, surface area, elemental analysis, TG, FT-IR and TEM indicated the successful tethering of organic amino group to the MCM-41 while the hexagonal structural character was mosdy retained. We prepared ruthenium based catalyst supported on functionalized MCM-41, and use it to the CO2 hydrogenation to formic acid. The results indicated that the immobilized ruthenium catalyst not only overcame the disadvantage of difficult separation from the reaction system and can be reusable, but also obtained higher activity than homogeneous counterparts. |
