摘要
多孔碳材料负载过渡金属氧化物因其环境友好、成本低、具有较好的催化性能等优点,被广泛应用于各类有机化学反应中。本文首先制备了Fe_2O_3纳米颗粒/氮掺杂多孔碳催化剂,进而利用Ullmann C-N偶联反应,研究了氮掺杂多孔碳材料载体在催化剂方面的作用,评估了其对不同底物的催化性能,并对其循环使用性能进行了测试。结果表明,Fe_2O_3/氮掺杂多孔碳对Ullmann C-N偶联反应中的几类反应的催化活性较高,可以达到90%以上,且具有较好的稳定性。
Transition metal oxides supported by porous carbon was widely used in a variety of organic reactions because they wereenvironment-friendly and low-cost,and had outstanding catalytic performance.In this paper,Fe2O3nanoparticles supported onnitrogen doped porous carbon were prepared.The effect of the nitrogen doped porous carbon support on the catalyst was studied byUllmann C-N coupling reaction.The activity of the catalysts,catalytic reaction kinetics and cycling performance were investigated.The results showed that Fe2O3/nitrogen doped porous carbon had a high catalytic performance for most Ullmann C-N couplingreactions,the yield was more than90%.Also the catalyst was stable for reuse in some degree.
