Abstract

Reaction steps that may ensue after the chemisorption of a hydrocarbon on a transition- metal surface are thermodynamically a sensitive function of temperature and pressure. Low temperatures and high H2 pressures, for example, favor CH bond formation. The unusual conditions employed for some surface science studies, Le., ultralow pressure and surface coverages of a monolayer or less, are not optimal for hydrogenation (CH bond formation), ...
