Abstract

Bare alumina shows surprisingly high activity in non-oxidative dehydrogenation of isobutane to isobutylene. The activity is related to surface coordinatively unsaturated Al sites (Alcus), which are created upon removal of OH groups during alumina treatment at high temperatures. Alcus and neighbouring lattice oxygen represent the active site for isobutane dehydrogenation.
