Studies of skeletal rearrangements of labeled hexanes on iridium and iridium-cobalt catalysts: Correlations between the product distributions and some structural information on the catalysts given by EXAFS

Isomerization of hydrocarbons using 13C-labeled molecules over both iridium and iridium-cobalt catalysts proceeds via a selective cyclic mechanism. By decreasing the iridium loading from 10 to 0.25 wt% or by adding cobalt to iridium, isomerization via bond-shift intermediates becomes more important....
