TORONTO There are many ways to reuse or outright reduce carbon emissions, and researchers at the University of Toronto may have found a way to do both.
Carbon splitting (using electricity to split a carbon dioxide molecule into carbon monoxide and oxygen) has traditionally been too expensive for widespread adoption in industry, and is impractical for capturing C[O.sub.2] out of the atmosphere.
If the C[O.sub.2] is siphoned directly from, for example, a factory's exhaust pipe, it never hits the atmosphere. And after being split, carbon monoxide can then be combined with hydrogen to make synthetic fuel, such as diesel.
A metal rod sends electricity through water and splits the water and C[O.sub.2] molecules into hydrogen, carbon monoxide and oxygen. Since carbon dioxide doesn't mix well with water (like carbonization in pop), this process can take a long time-the electricity will only split molecules that touch the catalyst rod-but researchers at the...
