Abstract
A method for removing NOX from gases is provided. A gas comprising NOX and/or SO.sub.2 is flowed behind a gas permeable anode. Air is simultaneously flowed behind the gas permeable cathode, and the cathode is separated from the anode by a liquid electrolyte. An external potential is applied between the anode and the cathode to bring about the oxidation of NOX and/or SO.sub.2 at the anode and the reduction of dioxygen at the cathode to yield nitric oxide and/or sulfuric acid, and hydrogen peroxide.
