Research on the Co-free Intelligent Catalyst 2003-01-0812

We have already reported that a LaFeCoPdO3 perovskite catalyst has the function for self-regeneration of Pd [1, 2, 3, 4, 5 and 6]. But cobalt was recognized as an environmental burden. In order to prepare for its practical application, we examined the composition of perovskite without cobalt.
In this paper, we have investigated the catalytic activity, the structural durability and the regenerative ability of Co-free perovskites LaFePdO3, in comparison with LaFeCoPdO3 and Pd/Al2O3. As a result, the structural durability of LaFePdO3 is high, and the light-off performance is excellent even after aging. “Co-free Intelligent Catalyst” is regarded as the next technology for practical use especially as it is efficient in the reduction of emissions at cold starting.
