The Self-Regenerative "Intelligent" Catalyst for Automotive Emissions Control

Abstract:

Article Preview

Co-free LaFePdO3 perovskite catalyst with the self-regenerative function of Pd was developed. This technology was named the “intelligent catalyst”. Suppression capacity for Pd particle growth and catalytic activity of the Co-free perovskite LaFePdO3 were compared with those of LaFeCoPdO3. It was confirmed that Pd particles on LaFePdO3 maintained a nano-particle size by the results of XAFS analysis and TEM observation after aging in engine exhaust gas at 900 °C, and LaFePdO3 demonstrated an excellent light-off performance. Further, the design configuration for LaFePdO3 in the washcoat was investigated to maximize the self-regenerative function under practical conditions.
