- It is critical to develop high performance three-way catalysts to meet increasing regulations around the world. It was found that a double-layered catalyst loaded with Pt and Rh suppresses Pt-Rh alloying, thereby improving catalytic performance. A double-layered catalyst has the effect of decreasing OSC performance, but this has been overcome by a newly developed Rh support and suppressed Pt grain growth. The developed catalyst is capable of lowering the amount of PGM required by approximately 40%.
