Unexpectedly high activity of bare alumina for non-oxidative isobutane dehydrogenation

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

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