Synthesis of mesoporous carbon nanotubes and their application in gas phase benzene hydrogenation

The multi-wall carbon nanotubes with pore diameter of 30-50 nm, synthesized by chemical vapor deposition over Co-La catalyst via decomposition of acetylene at 700°C0C, were employed as carrier of Ni-loading catalysts and exhibited excellent conversion of benzene and selectivity for cyclohexane in the gas phase benzene hydrogenation under atmospheric pressure.
