REDUCTION OF NITROUS OXIDE GAS AND ELECTROLYTIC CELL

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for surely, efficiently and continuously reducing nitrous oxide into nitrogen. SOLUTION: In the reducing method of nitrous oxide, a reaction chamber, which is in contact with an electrolytic cell 1 having an anode and a cathode 6 composed of a hydrogen occlusion material and uses the cathode as a partition wall is arranged, nitrous oxide in the reaction chamber is introduced to be brought into contact with the partition wall surface and continuous reduction is performed by hydrogen atom passed through the partition wall. Carrying platinum group metal black on the surface of the cathode opposed to the anode is preferable. The electrolytic cell for reducing nitrous oxide contains the anode and the cathode composed of the hydrogen occlusion material and serving as the partition wall and contains an electrolytic chamber 3 separated by the cathode and containing the anode and the reducing reaction chamber 4, in which nitrous oxide is supplied and reduced.
