Chemoselective semihydrogenation of alkynes to alkenes is a significant organic transformation and long challenge for heterogeneous catalysts. Herein, the PdAu alloyed nanoparticles were successfully deposited on the surface of cerium(IV) oxide nanorods ( NR ‐CeO 2 ) through an electroless chemical deposition process. Alloyed catalysts had an enhanced catalytic activity for hydrogenation of phenylacetylene and improved selectivity towards styrene, compared with the Pd/ NR ‐CeO 2 and Au/ NR ‐CeO 2 catalysts. The enhanced catalytic activity can be attributed to the alloying effects. Furthermore, the weak adsorption of styrene obtained from the modulated surface characteristics also benefits the improved chemoselectivity.
