Abstract

The mechanism of the dehydrogenation of methylcyclohexane (MCH) on Pt(111) has been studied using HREELS, TPD, and BPTDS. Upon warming a monolayer of MCH closed at 100 K, ≅55% desorbs and ≅45% dehydrogenates to a π-allylic species at ≅240 K. This π-allylic intermediate dehydrogenates further to a benzyl species at ≅310 K. Adsorbed benzyl is stable up to ≅450 K on Pt(111), but at higher temperatures further hydrogenation occurs.
