Cargnello and other researchers working to make liquid fuels from captured carbon imagine a carbon-neutral cycle in which carbon dioxide is collected, turned into fuel, burned again and the resulting carbon dioxide begins the cycle anew. <------
renewable cycle In this regard, the ability of the
new catalyst to produce gasoline from the reaction is a breakthrough, said Cargnello. The reactor in his lab would need only greater pressure to produce all the long-chain hydrocarbons for gasoline, and they are in the process of building a higher pressure reactor.
Gasoline is liquid at room temperature
“If we can make olefins from CO
2 to make plastics,” Cargnello noted, “we have sequestered it into a long-term storable solid. That would be a big deal.”
The key to the remarkable increase in
reactivity is that layer of porous plastic on the
ruthenium, explained lead student author
Chengshuang Zhou, a doctoral candidate in Cargnello’s lab, who conducted the search and experimentation needed to refine the new coating. An uncoated catalyst works just fine, he said, but only produces
