Intelligent Catalyst

摘要

We have developed a new Perovskite-based catalyst, which regenerates itself without any auxiliary treatment, in direct reaction to the inherent fluctuation between reductive and oxidative atmospheres in the exhaust gas from state-of-the-art gasoline engines. As palladium reversibly moves back and forth between inside and outside of the Perovskite crystal, the particle growth of palladium can be suppressed.
