Synthetic mulita reduces up to 45% more pollutants than metal catalyst.
Mineral can be produced from topaz.
Engineers at the University of Texas, USA, say they have identified a material capable of reducing the pollution produced by diesel-powered cars.
The element, called a type of mineral mulita, can replace the platinum expensive metal used in diesel engines to control the amount released in the air pollution.
The study was published in the journal "Science" this Friday (17). According to researchers, a synthetic version of mulita reduces up to 45% more pollution than the platinum used in catalytic converters for vehicles.
One of those responsible for research, professor Kyeongjae Cho, University of Texas, emphasized the ease of production of mulita, told the website. The mineral is rarely found in nature and can be produced from topaz.
"Many methods of controlling pollution from cars or use renewable energy require rare or precious metals," said Cho. "Our goal is to end the need for these metals and replaces them with minerals and oxides that can be easily found or obtained."
The material "alternative" will be marketed under the name of Noxicat, says the professor. He and his team hope other uses of mulita being identified as the creation of batteries.
