Abstract

(Asymmetrical Pd@Ag core)@(CeO2 shell) nanostructures are successfully fabricated via a clean and facile modified autoredox reaction by the preaddition of Pd seeds in the growth solution. In a subsequent catalytic test, it is found that the as-obtained bimetallic core@shell nanoparticles exhibit excellent catalytic performance in semihydrogenation of alkynes. The trade-off between selectivity and activity is well realized.
