  • Patent number: 11813594
    Abstract: A heterogeneous catalyst for substrate-directed hydrogenation includes bimetallic nanoparticles of M1-M2, wherein M1 is a noble metal and M2 is a first-row transition metal. The bimetallic nanoparticles are on a substrate and atoms of both the noble metal and the first-row transition metal are distributed across surfaces of the bimetallic nanoparticles. The heterogeneous catalyst may be produced by providing M1-M2 bimetallic nanoparticles on a substrate to produce an intermediate composition, and performing a reduction process on the intermediate composition such that atoms of both the noble metal (M1) and the first-row transition metal (M2) are distributed across surfaces of the bimetallic nanoparticles and thereby form the heterogeneous catalyst. The catalyst may be used for performing directed hydrogenation of a substrate.
