| Outline of Final Research Achievements |
For the simultaneous purification of NO, CO and HC in automotive exhaust, a new three-way catalysis with a tandem structure was developed. In the former stage, CO oxidation was carried out over Cr-Cu/CeO2, resulting in the decrease of CO and O2 concentration. The gas which contained stoichiometric NO, C3H6 and O2 was consecutively introduced to the latter stage and NO-C3H6-O2 reaction over Pd/CeO2 was carried out for the simultaneous purification of NO and HC. The results demonstrated that the tandem structure is one of useful ways for the development of new three-way catalysis.
