| Abstract: | For the development trend of engine, the species of surface active oxygen and their catalytic activity were discussed combining with the research progress of vehicle exhaust catalyst. Besides these, the production, desorption, storage, migration of active oxygen species and their relationships were described, the research status of their behavior and mechanism in catalytic reaction was summarized, and finally some existing problems and suggestion in the research were put forward. |
