| 摘 要： | 自制了一种新型Pd/MCM 41非均相催化剂,BET和XRD分析表明其具有长程有序的柱形中孔结构,孔道较为规整,该催化剂在碘苯偶联制备联苯的反应中表现出较高活性.添加Al进入MCM 41骨架,获得Al MCM 41,当Si∶Al的摩尔比值为60时,在14%Pd/Al MCM 41上联苯的得率为41 6%,有望替代传统Ullmann反应中的均相催化剂.

| Abstract: | The nanosacle Pd/MCM- 41 catalyst has been prepared . BET and XRD indicated that the catalyst had a highly mesoporous regular structure. The catalyst showed high catalytic activity in preparation of iodobenzene homocoupling. When Al atoms were incorporated into MCM-41 framework and Si/Al molar ratio is 60 with 14% loading of Pd, the Pd/Al-MCM-41 exhibited higher activity and better selectivity to biphenyl and the yield of biphenyl may reach 41.6%, which shows its good potential to match the homogeneous catalyst in traditional Ullmann coupling reactions. |
