Summary:Semi-hydrogenation usually requires an effective catalyst to ensure selectivity, especially when reducible
 groups coexist in a molecule. Pd is widely used in the semi-hydrogenation of alkynes to synthesize
 alkenes, but the selectivity control is still challenging. Herein, we design a catalyst with a semi-encapsu
lated PdRh alloy heterojunction in a carbon layer for the selective semi-hydrogenation of 3-nitrophenyla
cetylene (3-NPA). Benefiting from the presence of a PdRh alloy heterojunction and a semi-encapsulated
 structure, the catalyst delivers good selectivity and maintains high activity. In addition, the carbon shell
 can ensure the stability of the catalyst and prolong the service life. This study provides ideas for the
 rational design of a catalyst to achieve a selective hydrogenation reaction for practical applications.
