Angewandte 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.
