A series of active‐carbon‐supported PdPb and PdCu bimetal catalysts were prepared for the selective semihydrogenation of alkynes in the liquid phase. The Pd 0.33 Pb 0.67 /C catalyst showed the best performance for various alkynes under mild reaction conditions (room temperature and ambient H 2 pressure) and achieved 100 % conversion with 98 % selectivity to alkenes. In particular, over‐hydrogenation was avoided at complete alkyne conversion.
