Managing the atom migration in zeolite-encapsulated K–Pt–Sn clusters for non-oxidative dehydrogenation of ethane (opens in new tab)

In various heterogeneous catalytic processes, the active sites are often composed of two or more metal elements to balance activity, selectivity and durability. However, precisely controlling the compositions of supported bimetallic or multi-metallic clusters and maintaining their stability under high-temperature reaction conditions presents a substantial challenge. Here we show that the migration of K and Sn species during ethane dehydrogenation over multiple reaction–regeneration cycles agg...
