| 中文摘要: |
| 水热条件下，ZrCl4 与2, 2’-联吡啶-5, 5’-二甲酸(dipydc)配位聚合形成Zr基金属-有机框架化合物(Zr-MOF)。将HAuCl4乙醇溶液引入Zr-MOF中，Au3 离子被原位还原得到Au/Zr-MOF催化剂。由于高度分散的极细的金纳米粒子以及底物在催化剂微孔孔道中的吸附和扩散，Au/Zr-MOF催化剂在各种水介质的A3-偶联反应中显示出较高的活性。该催化剂便于回收和套用，在重复使用5次后，催化活性没有显著地降低。 |
| 英文摘要: |
| Zr-based metal–organic framework (Zr-MOF) was synthesized by coordinated polymerization between ZrCl4 and 2, 2’-bipyridine-5, 5’-dicarboxylate acid under hydrothermal condition. The Au/Zr-MOF was then prepared by in situ reduction during impregnation of Zr-MOF with HAuCl4 ethanol solution. The as-prepared catalyst exhibited high activity in various water-medium A3-coupling reactions owing to the uniform dispersion of Au nanoparticles with very small size and the facilitated diffusion and adsorption of reactant molecules in the micropores. Moreover, the catalyst could be easily recycled and used repetitively for at least 5 times without significant decrease in activity. |
