| 摘要 |
Apparatus for the reduction of nitrogen oxides in gas streams are disclosed comprising an oxygen ion-conducting substrate, an anode disposed on the substrate, a cathode disposed on the substrate, and a voltage source connected to the anode and the cathode in which the cathode is comprised of gold so that the nitrogen oxides are adsorbed and dissociated on the cathode, nitrogen may recombine into nitrogen gas on the cathode, and oxygen ions are transported through the substrate from the cathode to the anode. Methods for the reduction of nitrogen oxides in gas streams are also disclosed. |
