SSZ‐13 Zeolite with Isolated Co2+ Sites as an Efficient and Durable Catalyst System for Non‐Oxidative Ethane Dehydrogenation

open access: yesAngewandte Chemie International Edition, EarlyView.
Catalysts with the isolated Co2+ species in the 6MR (Co2+─Z2) and 8MR ([Co(OH)]+─Z) windows of the SSZ‐13 zeolite were synthesized for non‐oxidative ethane dehydrogenation to ethene. The Co2+─Z2 species demonstrate an unexpectedly high rate of ethene formation in comparison with the ([Co(OH)]+─Z species.
