| 英文摘要 | selective decomposition of nitrogen monoxide (no) in the presence of oxygen was studied on electrochemical cells composed of yttria-stabilized zirconia (ysz), electrodes, and surface oxide layers added. decomposition activity was first measured on metal oxide/pd(cathode)/ysz/pd(anode) at 773-973 k and 3.0 v of applied voltage in a flow of 50 ml/min containing 1000 ppm of no and 6% of o-2 in helium. coating of various metal oxides onto the cathode electrode greatly changed the decomposition activity; the order was ruo2>>pt>rh2o3>ni>none>ag>wo3. the activity of the system modified by ruo2 has been investigated as a function of the kind of electrode, the applied voltage, and the reaction temperature. the cell of ruo2/ag(cathode)/ysz/pd(anode) was found to show the most excellent activity among the cells examined. the conversion of no and the current efficiency for no decomposition reached 31.8% and 11.8%, respectively, at 7 ma/cm(2) of current density induced by 2.2 v and 773 k, and the no decomposition proceeded selectively about 13 times than the o-2 decomposition under the reaction condition.
