A heterogeneous catalyst for substrate-directed hydrogenation includes bimetallic nanoparticles of M
1
-M
2
, wherein M
1
is a noble metal and M
2
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 M
1
-M
2
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 (M
1
) and the first-row transition metal (M
2
) 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.
