The process of directly using atmospheric H2 for the catalytic semi-hydrogenation alkynes to alkenes has significant applications in polyolefin industry. Herein, we report a facile approach synthesize hierarchical carbon-encapsulated Pd catalyst highly selective nitrophenylacetylene. featured structure (Pd@NG)/(Pd@C), which demonstrated that an oligo-layer nitrogen-doped graphene (NG)-encapsulated particles are supported on carbon matrix, semi-embedded by another type particle. catalyst, named Pd@NC, achieved 99% selectivity nitrostyrene at 97% nitrophenylacetylene conversion and excellent stability. A good arose from bridging effect porous carbon, where hydrogen activation alkyne hemihydrogenation took place palladium NG, respectively. NG layer provided protection against over-hydrogenation reaction.
