A method of reducing nitrous oxide which comprises introducing nitrous oxide into a reaction chamber disposed in contact with an electrolytic chamber having an anode and a cathode comprising a hydrogen-absorbing material, the cathode serving as a diaphragm separating the reaction chamber and the electrolytic chamber, and contacting the nitrous oxide with the diaphragm to thereby continuously reduce the nitrous oxide with hydrogen atoms electrolytically generated on the cathode, absorbed by the hydrogen-absorbing material and passing through the diaphragm. The cathode preferably has catalyst comprising a platinum group metal black deposited on the side of the cathode opposite the anode. Also disclosed is an electrolytic cell for the reduction of nitrous oxide partitioned with a diaphragm into an electrolytic chamber having an anode and a reduction reaction chamber, the diaphragm comprising a hydrogen-absorbing material, and the side of the diaphragm facing the electrolytic chamber serving as a cathode.
A method of reducing nitrous oxide which comprises introducing nitrous oxide into a reaction chamber disposed in contact with an electrolytic chamber, said electrolytic chamber containing an electrolyte and having an anode and a cathode comprising a hydrogen-absorbing material, said cathode serving as a diaphragm separating said reaction chamber and said electrolytic chamber, electrolytically generating hydrogen on the cathode in said electrolytic chamber, and contacting the nitrous oxide with said diaphragm to thereby continuously reduce the nitrous oxide with hydrogen atoms electrolytically generated on the cathode, absorbed by said hydrogen-absorbing material and passing through said diaphragm to reach the reaction chamber.
A method of reducing nitrous oxide contained in a gas or a liquid to be treated, using an electrolytic cell partitioned with a diaphragm into an electrolytic chamber and a reduction reaction chamber, said diaphragm comprising a hydrogen-absorbing material, said electrolytic chamber including an anode and containing an electrolyte, and the side of the diaphragm facing the electrolytic chamber serving as a cathode, which method comprises:
