▎ 摘　　要

Palladium nanoparticles (NPs) dispersed on a few-layer graphene (FLG) surface were investigated as a catalyst for the liquid-phase selective hydrogenation of the C=C bond. The Pd/FLG catalyst exhibits a high hydrogenation activity compared to those obtained on the 1D support, i.e. carbon nanotubes. The high hydrogenation activity and C=C bond hydrogenation selectivity was attributed to the 2D morphology of the support with an extremely high accessible surface for reactant access and for desorption of the intermediate products before secondary hydrogenation.
