The nature of the active compound in Li doped MgO was investigated by comparing the activity and deactivation of Li/MgO catalysts with that of Li2CO3 supported on an inert carrier (ZrO2). The conclusion is that Li2CO3 itself is a very active catalyst (or a catalyst precursor). Also the role of the catalyst in the oxidative coupling of methane was determined: The selectivity of the active catalyst is mainly due to a very high production rate of methyl radicals.
