The use of pure or high levels of noble metals (Pt, Rh, Pd) in the existing commercial catalysts are increasingly unsustainable in many aspects.
About
In this new technology, the use of noble metals in combination with non-noble metals in the catalysts reduces the content of noble metals in the catalysts by 30 to 70% in comparison with the use of pure noble metals in existing catalysts in many emission control systems. The reduction of the noble metals in the catalysts will reduce the cost of catalysts under the same catalytic performance condition in comparison with existing high-noble-content catalysts.
Key Benefits
In comparison with existing commercial catalysts for 3-way catalytic converters and related emission control systems under comparable catalytic performances, the major advantages include low noble metal content in the catalysts and low cost in the catalyst products.
