摘　　要：制备了Fe Cu/SiO2 催化剂 ,用该催化剂在 5 5 0℃裂解乙烯制得了碳纳米管 ,电镜结果显示碳纳米管直径在 15～ 2 0nm之间。在钌络合物催化的环己烯氧化反应中加入碳纳米管 ,使环己烯的转化率达到 99 0 % ,Ru催化剂TOF达到了 2 90 0 0h 1。结果表明碳纳米管可以提高钌络合物的催化氧化活性 ,并且抑制产物中环己烯醇的进一步氧化。Fe Cu/SiO 2 particles were prepared and used as catalyst for the decomposition of ethylene at 550℃ to form carbon nanotubes (CNTs) TEM image showed the diameter was about 15～20nm and the XRD pattern compared with graphite showed higher degree of graphitization The Ru complex catalyzed the oxidation of cyclohexene by molecular oxygen at 130℃ to the products including 2 cyclohexen 1 one, 2 cyclohexen ol and 1,2 cyclohexandiol The addition of CNTs to the reaction system can increase the activity of the Ru complex and the selectivity of 2 cyclohexen 1 ol
