▎ 摘　　要

NOVELTY - Separating hydrogen and oxygen evolution in electrolytic water comprises alternately and circularly performing the hydrogen evolution reaction in the hydrogen evolution reaction, taking carbon electrode as anode, taking hydrogen evolution catalytic electrode as cathode, electrolyzing electrolyte containing soluble ion; the surface of the hydrogen evolution catalytic electrode is subjected to electrochemical reduction reaction to generate hydrogen, the carbon electrode electrochemically absorbs soluble ion in the electrolyte in the oxygen evolution reaction, taking carbon electrode as cathode, oxygen evolution catalytic electrode as anode, electrolyzing the electrolyte, the surface of the oxygen evolution catalytic electrode generating electrochemical oxidation reaction to generate oxygen, the carbon electrode electrochemical desorption of the soluble ion adsorbed in the hydrogen evolution reaction. USE - The method is useful for separating out hydrogen and oxygen evolution in electrolytic water. ADVANTAGE - The method can work under the environment of full pH with excellent electrolytic water characteristic, which can avoid the simultaneous generation of hydrogen and oxygen, and improve the efficiency of the electrolytic water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for device for separating out hydrogen and oxygen evolution in electrolytic water.
