Highly stable Li-doped magnesium oxide catalyst for oxidative conversion of methane to higher hydrocarbons

A Li-doped MgO catalyst, when prepared by impregnation of magnesium acetate with aqueous lithium acetate (with a Li to Mg molar ratio of 0.1 : 1) followed by calcination in air at 750 °C, shows no change in its initial high activity and selectivity in oxidative conversion of methane to higher hydrocarbons, for a long period.
