Abstract
Mesoporous carbon (MC) has been successfully synthesized via the soft template method and further impregnated with monometallic Ni and bimetallic Ni-Co to give Ni-modified MC (Ni/MC) and NiCo/MC, respectively. The modified MC materials were characterized using XRD, SEM-EDX, SAA, and TEM. The results of the TEM analysis showed that the metal was homogeneously distributed on MC with the average particle sizes of Ni and bimetallic NiCo being 23.1 and 10.4 nm, respectively. The results of BET analysis show that the materials have a high surface area of 304, 289, and 313 m²/g for MC, Ni/MC, and NiCo/MC, respectively. Both Ni/MC and bimetallic NiCo/MC were then used as catalysts in phenylacetylene hydrogenation under atmospheric hydrogen pressure. [ABSTRACT FROM AUTHOR]
