Few-layer graphene supporting palladium nanoparticles with a fully accessible effective surface for liquid-phase hydrogenation reaction
Palladium nanoparticles (NPs) dispersed on a few-layer graphene (FLG) surface were investigated as a catalyst for the liquid-phase selective hydrogenation of the CC 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 CC 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.
