Selective hydrogenation reaction over supported metal nanoparticles (NPs) through activation of molecular H 2 is very demanding in the context of maintaining atom efficiency in chemical reactions. Although high selectivity is difficult to achieve in the reaction, but it is very challenging. In this research, we separately deposited Pd and Pt NPs on nanoporous hollow polymer tubes (PP‐3) and studied their efficiency in hydrogenation of α,β‐unsaturated aldehydes as substrates. We found hydrogenation selectivity over these two types of catalysts (Pd@PP‐3 and Pt@PP‐3) were entirely different. Pt@PP‐3 shows high selectivity in the hydrogenation of C=O bonds, producing unsaturated alcohol in high yield, whereas Pd@PP‐3 only hydrogenates C=C bonds and forms saturated aldehyde as the major product. Pd@PP‐3 and Pt@PP‐3 were thoroughly characterized by PXRD, N 2 sorption, TEM, XPS, CO stripping experiment and in‐situ CO adsorption FT‐IR studies. Our research implies the utility of porous organic polymers as support for metal NPs mediated hydrogenation reactions.
