Low-Temperature NO[sub x] Decomposition Using an Electrochemical Reactor

We attempted to fabricate and evaluate a decomposition electrochemical reactor with an additional adsorption layer on a multilayer catalytic cathode and investigated a cell operating method to achieve low-temperature operation. To clarify the capability of a adsorption layer, we carried out the decomposition measurements of the cell. As a result, adsorption layers have improved the decomposition properties, though the current values of each cell were almost the same. The decomposition by a -doped based cell with a adsorbent took onset around . It was clarified that the starting temperature and the efficiency of the decomposition are heavily dependent on the adsorptivity of adsorbent and the cell operating voltage mode.
