Success in Development of Exhaust Gas Catalyst with Thermal Agglomeration Resistance 10x Higher than Conventional Materials: A Way to Minimize Rare-Metal Use| Research

2 Nov, 2010

An exhaust gas catalyst material, with approximately 10 times greater thermal agglomeration resistance than conventional materials, has been developed. This remarkable improvement opens the road to a large reduction in the amount of rare metals used in exhaust gas purification technologies.

Figure 1. Newly developed artificial "Metalic Cell". Automotive exhaust gas is sucked into the cell through the channel 1/1000mm in diameter opened in the cell wall, and discharged after purification.
