Abstract Developing robust electrocatalysts for efficient semi‐hydrogenation of alkynes to markedly important alkenes is highly desirable in both research and industry areas. In this work, it reported that palladium mesoporous nanospheres (Pd MSs) with electron‐rich active sites perform perfectly as cathode electrocatalyst electrochemical water. comparison its counterparts, Pd MSs hold remarkable conversion (97%), superior selectivity (98%), good operation stability selective p‐aminophenylene. High performance assigned within mesopores not only favor the formation H* but also accelerate desorption p‐aminostyrene. Meanwhile, are various terminal different substituents. It thus expected can be demonstrated an alternative catalyst design paradigm other hydrogenation reactions.
