Title: Oxidative conversion of methane to oxygenates

Abstract

A method of converting methane to an oxygenate. The method includes converting methane to an oxygenate with a transition metal ion loaded zeolite catalyst in an aqueous medium in the presence of gaseous O2 and CO at a temperature lower than 200° C. Also disclosed are a two-metal ion zeolite catalyst for converting methane to methanol and a method for preparing the two-metal ion zeolite catalyst.
