| Abstract: | 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 |
