Constrains to improve hydrogenations

Nature Catalysis, Published online: 28 April 2026; doi:10.1038/s41929-026-01520-z The hydrogenation of pyridine molecules to their corresponding piperidines remains a particularly challenging transformation. Now, a class of catalytic materials based on the encapsulation of metal nanoparticles within zeolite frameworks has emerged as a promising solution to this challenge.
