Abstract: A method of forming ethylene is disclosed. The method includes introducing oxygen-containing molecules to a first electrode of an electrochemical cell including the first electrode, a second electrode, and an electrolyte between the first electrode and the second electrode. The second electrode includes at least one catalyst material formulated to accelerate oxidative coupling of methane (CH4) (OCM) reaction rates to produce C2H4 from CH4 and oxygen ions. The method further includes introducing CH4 to the second electrode of the electrochemical cell. The method also includes applying a potential difference in electrolysis mode between the first electrode and the second electrode of the electrochemical cell. The oxygen-containing molecules interact with the second electrode to produce O2? through reduction of the oxygen-containing molecules, the O2? are transported through the electrolyte, and C2H4 is produced at the second electrode through OCM.
