Abstract

The oxidative dimerization of methane to ethane over thin-film MgO and Li/MgO catalysts prepared under well-controlled, ultrahigh vacuum (UHV) conditions has been studied using a combination UHV/reactor cell system that allows elevated pressure kinetic studies and surface science techniques to be employed. Reactions investigating temperature, pressure and pretreatment activation have been performed to determine ethane dependence on each reaction parameter. Agreement between turnover frequencies, activation energies and lithium promotional effects of the thin-film MgO and previously reported results for powdered MgO indicates that the thin-film catalyst is an excellent model catalyst for the oxidative coupling of methane.
