| 摘 要： | 采用两种方法制备了功能化MCM-41固载的钌基催化剂，并用原子吸收光谱，紫外可见光谱以及红外光谱等手段对其进行表征。结果表明,钌基在功能化MCM-41上顺利固载。将这两种固载的钌基催化剂用于二氧化碳加氢合成甲酸反应，发现在较低反应温度和较低氢分压下，固载的RuCl2(PPh3)3催化剂表现出更高的催化活性，在反应温度80℃，H2分压5MPa, CO2分压8MPa下，甲酸转化数达到1275。固载的RuCl2(PPh3)3催化剂也表现出很好的重复再用性。

| Abstract: | Two kinds of immobilized Ru catalysts were synthesized by anchoring different ruthenium complexes on the functionalized mesoporous MCM-41 and then characterized with elemental analysis, atomic absorption spectrophotometer, UV-Vis and FT-IR. Hydrogenation of carbon dioxide to formate was investigated over these catalysts in CO2-expanded solvent. The effects of solvents and bases on the catalyst activity were also examined. These two catalysts are different in their activities and stabilities, especially at lower temperature and hydrogen partial pressure. High formate yield is obtained and no byproduct is detected. The immobilized Ru catalysts are promising in industry due to the facility in catalyst separation and reuse. |
