Semihydrogenation of alkynes to produce alkenes is very important in the industry; however, over‐hydrogenation heavily complicates the postprocesses, which are highly energy consuming and not environmentally friendly. One of the most efficient pathways to solve this challenging issue is to develop highly selective catalysts that could only hydrogenate alkynes and are inactive in hydrogenation of alkenes. This work presents herein an efficient catalyst, consisting of in situ created PdS 0.53 nanoparticles as the redox‐active sites inside the defect pores of metal–organic framework UiO‐66, which demonstrates very high alkene selectivity (up to 99.5%) in semihydrogenation of easily over‐hydrogenated terminal alkynes. In contrast to the traditional catalysts, strict control over the reaction time becomes the nonessential condition because the catalyst system is almost inactive in hydrogenation of alkenes. Therefore, this paradigm work provides a practically applicable pathway for the development of efficient catalysts with unique catalytic properties for selective semihydrogenation reactions.
