Researchers have designed a metal oxide catalyst for
removing pollutants from diesel engine exhaust that could potentially replace
costly platinum catalysts.
Engineers at a company co-founded by a University of Texas
at Dallas professor have identified a material that can reduce the pollution
produced by vehicles that run on diesel fuel.
The material, from a family of minerals called oxides, could
replace platinum, a rare and expensive metal that is currently used in diesel
engines to try to control the amount of pollution released into the air.
