Nature Catalysis, Published online: 26 May 2026; doi:10.1038/s41929-026-01538-3 PtSn catalysts are most effective for propane dehydrogenation but structural tunability remains challenging. Now the use of molecular complex precursors unlocks access to subnanometre alloyed PtSn clusters within silicalite-1. The Pt in the clusters undergoes diverse and rapid interconversion among different electronic structures, resulting in high performance and stability.
